Description:
Batch adsorption of the chromium(VI) onto Moroccan stevensite pillared by Keggin aluminium hydroxypolycation (Al-stevensite) and cationic surfactant cetyltrimethylammoniumbromide (CTA-stevensite) was investigated. The results showed that the CTA-stevensite has a higher affinity than that of Al-stevensite for chromium(VI) adsorption. The adsorption capacities for natural stevensite, Al-stevensite and CTA-stevensite calculated according to the Dubinin-Kaganer-Radushkevich isotherm (DKR) are 13.7, 75.4 and 195.6mmolkg^-^1, respectively. The study of the pH effect showed that the optimal range corresponding to the Cr(VI) maximum adsorption on Al-stevensite is pH 3.5-6 and that on CTA-stevensite is pH 2-6. The adsorption rates evaluated according to the pseudo-second-order model are 7.2, 207.2 and 178.5mmolkg^-^1min^-^1 for the natural stevensite, Al-stevensite and CTA-stevensite, respectively. The low values of the adsorption energy calculated by (DKR) suggest that anion exchange is the main mechanism that governs the chromate adsorption.

Description:
The surfactant to dye binding degree (SDBD) method was extended for the first time to the determination of cationic amphiphiles. For this purpose, Cresyl Violet (CV) and sodium dodecylsulphate (SDS) were selected as dye and reactant surfactant, respectively. This chemical system was used for the determination of cationic surfactants in pharmaceuticals. The approach was based on the competition established between the dye and cationic analytes to form mixed aggregates with the anionic surfactant (SDS-CV and SDS-analyte), which resulted in an increase of the amount of SDS required to reach a given SDS-CV binding degree. The feasibility of the proposed method to determine quaternary ammonium surfactants belonging to different structural groups (alkyldimethylbenzylammonium chlorides, alkyltrimethylammonium bromides and alkylpyridinium chlorides) in a wide variety of pharmaceutical formulations (solutions, creams and powders) was proved. The analytical features of the SDBD method (versatility, high precision and selectivity, ruggedness, rapidity, simplicity and low cost) made it an advantageous alternative to the conventional methods used in cationic surfactant quality control.

Description:
The effect of co-occurring inorganic solutes existence in feed water on the removal of arsenic (V) and permeate flux was investigated for the treatment process using a cationic surfactant cetylpyridinium chloride (CPC) and a 5 kilo-Dalton (kDa) polyethersulfone (PES) membrane. Simulated water and well water (Washoe County STMGID #9 operational well, Nevada) were used for this study. The concentrations of arsenic ([As]"F = 0-105 @mg/L) and inorganic solutes ([HCO^-"3] = 0-4.1 mg/L, [HPO^2^-"4] = 0-0.3 mg/L, [H"4SiO"4] = 0-90 mg/L, and [SO^2^-"4] = 0-400 mg/L) in simulated feed water were varied. The pH level of simulated feed water was adjusted to 8 since the well water pH was around 8. The arsenic concentration in the well water was 73 @mg/L. The concentrations of carbonate, phosphate, silicate, and sulfate in the well water were 1 mg/L, 0.17 mg/L, 69 mg/L, and 8.2 mg/L, respectively. PES membrane without surfactant micelles was found to be ineffective for arsenic removal. The highest arsenic removal in the presence of inorganic solutes is 25%, corresponding to a permeate water arsenic concentration of 30 @mg/L which is well above the new maximum contaminant level (MCL) of 10 @mg/L. With the addition of 10 mM CPC to the feed water, the arsenic removal efficiency is significantly increased ranging between 78.1% and 100%. The arsenic removal efficiency was found to be dependent on the feed water arsenic and co-occurring inorganic solute concentrations. Except for one UF experiment performed with the simulated feed water containing 105 @mg/L arsenic and 400 mg/L SO^2^-"4 (23 @mg/L arsenic in permeate water), all the other UF experiments produced permeate water with arsenic below the new MCL. The presence of HCO^-"3, HPO^2^-"4, and H"4SiO"4 species in feed water does not affect the arsenic removal efficiency (100%) except in one case (99% removal efficiency for the feed water containing 105 @mg/L arsenic and 90 mg/L H"4SiO"4). The experiments performed with well water result in almost 100% arsenic removal (arsenic level in permeate water is below the detection limit of ICP-MS, 1 @mg/L). Furthermore, absolute permeate flux was also found to be dependent on the feed water arsenic and co-occuring inorganic solute concentrations. An increase in feed water arsenic concentration results in a decrease in the permeate flux. For the experiments performed with simulated water containing CPC and arsenic, the permeate water flux is 56.5 +/- 2.5% of ultra clean water flux. The permeate flux reduces further as the co-occuring inorganic solute concentration or the total dissolved solid in feed water increases. It is 43.5 +/- 3.5%, 45.5 +/- 7.5%, 43.5 +/- 6.5%, and 37.5 +/- 5.5% of the ultra clean water flux for the simulated water containing HCO^-"3, HPO^2^-"4, H"4SiO"4 and SO^2^-"4 species, respectively. With the well water, permeate flux was found to be 33% of the ultra clean water flux. Only 1.52 +/- 0.33% of the surfactant molecules used were detected in permeate water. Surfactants in permeate water can be further separated and reused in the feed stream.

Description:
Iron in its familiar form exists in the +2 and +3 oxidation states, however, higher oxidation state of iron +6, ferrate(VI) (Fe^V^IO"4^2^-) can be obtained. The high oxidation power of ferrate(VI) can be utilized in developing cleaner (''greener'') technology for remediation processes. This paper demonstrates the unique property of ferrate(VI) to degrade almost completely the cationic surfactant, cetylpyridinium chloride (C"5H"5N^+(CH"2)"1"5CH"3.H"2O Cl^-, CPC). The Rate law for the oxidation of CPC by ferrate(VI) at pH 9.2 was found to be: -d[Fe(VI)]/dt=k[Fe(VI)][CPC]^2. Ferrate(VI) oxidizes CPC within minutes and molar consumption of ferrate(VI) was nearly equal to the oxidized CPC. The decrease in total organic carbon (TOC) from CPC was more than 95%; suggesting mineralization of CPC to carbon dioxide. Ammonium ion was the other product of the oxidation. This is the first report in which Fe^V^IO"4^2^- ion opens the pyridine ring and mineralizes the aliphatic chain of the organic molecule giving inorganic ions.

Description:
Four experimental plots located in Granada (Spain) were used to investigate the potential movement of the insecticide methidathion during three treatments in a period of three years. To increase pesticide soil retention a municipal biosolid and the cationic surfactant, tetradecyl trimethyl ammonium bromide (TDTMA), were used as soil amendments. The presence of the insecticide was monitored in soil and water samples at different depths up to one meter. Soil solution was sampled by ceramic suction cups installed at three depths (25, 75 and 100cm). No effect of the amendments on pesticide mobility was observed. Experimental results showed that pesticide leaching occurred in the upper soil layer. Although some sporadic high water soil concentrations were found, these were attributed to preferential flow processes. This was confirmed by the absence of high pesticide concentration in soil samples at similar depths. Pesticide mobility was mainly affected by the irrigation employed. Experimental results were compared with theoretical data simulated with the mathematical model FocusPelmo. The resemblance between theoretical and experimental soil data seems to confirm the preferential flow processes. Otherwise, the lack of fit between the soil water data were attributed to the ceramic devices employed, that could suffer an ''ageing process'' which would cause bias in the determinations.

A prolific author, gifted outdoor photographer and a nationally-renowned river conservationist, this is Tim Palmer's ode to America's bountiful and beautiful rivers. No one writes about rivers -- or captures their magical essence in photos -- like Tim, because no one knows and cares as much about them as he clearly does. If you love rivers, then you will love this book! Learn more about Tim's love affair with rivers by visiting: www.americanrivers.org/palmerprofile.

Brilliant Set of Photographs.......2006-09-25

A photographer with the eye of an artist, Tim Palmer has spent a lifetime photographing rivers. He has gone to extremes to get just the right view, at the right time of day, the right time of the year. He has combines these photographs with prose that is almost poetic to add in our understanding of what he sees, what he feels.

I don't know just how many states he covers in these photographs, but perhaps the most dramatic pictures are those taken in Alaska. From the bears fishing for salmon, to the young wolf who has found a drowned sheep, the broad expanse of the mountains the pictures show nature at its most attractive.

Surprisingly though his pictures show the beauty that remains in the rivers of the lower 48. In spite of what has happened in terms of polution, concrete channalizing by the Corp of Engineers, there is beauty to be found. And Mr. Palmer has the eye to find that beauty.

Natural Allies: Conservationists and Ranchers .......2007-08-08

I've long held to the common environmentalist's view that cattle and sheep grazing in the arid west was an environmental disaster, destroying vegetation, habitat, and displacing wild animals. New research and books like this have changed my opinion. Sayre, a well know dry-land ecologist, profiles six ranches in Arizona and New Mexico and describes how ranchers have enhanced their grazing land with environmentally-sound techniques. This sounds like dry stuff, but this attractive book and a not-too-technical text make the subject interesting.

Traditionally, ranchers and environmentalists were sworn enemies with nothing but contempt for each other. This was silly. The threat to the open land of the West now is 2-acre "ranchettes" and galloping suburbanization. Preserving the big ranches from "development" is the best means we have to ensure that the lone prairies remain for future generations. What we now see, with books like this one, is science rather than emotion being used to evaluate how ranch land can be improved and preserved -- or at least damage minimized -- through better techniques of grazing cattle.

The New Ranch Handbook is large-format; the cover features dramatic before and after color photos of good and bad grazing; and 100 good black and white photos are scattered among 100 pages of text. It's an excellent book for the dry-land rancher, the environmentalist, or people like me who just like to know what we're looking at as we explore the great American Southwest.

Death of a Canyon.......2007-06-10

This not a book about photography and should not be purchased just for the "pictures". It is literally a memorial to the death of Glen Canyon. It is a reminder of our obligation to stay informed.

Glen Canyon Dam should never have been built and would never be built today. The American people would never stand for it. Ironically and sadly, it was the loss of Glen Canyon that inspired many to say, "Never again." When the Bureau of Reclamation attempted to follow Glen Canyon Dam with a series of dams down stream in the Grand Canyon, the agency met a solid wall of opposition. In ways, the river still flows free through the Grand Canyon because of the sacrifice that was made with Glen Canyon.

Even former staunch proponents of Glen Canyon Dam lived to regret their support. As late as 1974, Senator Barry Goldwater still felt the dam was an improvement over the untamed river. But by the mid-80s, he felt otherwise. In one interview, in fact, Goldwater lamented that if he could change just one Senate vote he'd cast in 30 years, it would have been his vote to approve construction of Glen Canyon Dam.

Sad.

Historically valuable, photographically bland.......2005-09-30

"The Place No One Knew" is the famous book that comes up anytime someone mentions the submersion of Glen Canyon. It was the Sierra Club's--and the environmental movement in general's--first major statement on the construction of Glen Canyon Dam, the flooding of Glen Canyon, and the filling of Lake Powell.
The book is a companion, or I should say the polar opposite, of "Lake Powell: Jewel of the Colorado," a book by Floyd Dominy, then Commisioner of the dam-building Bureau of Reclamation.
Both books are basically propaganda, though for seperate sides of the same issue; both feature scenic photos of a place, praising text, and pertinent quotes.
Glen Canyon was referred as to "the place no one knew" because its lack of national park status (and protection) was a major factor in its being inundated by the trapped water of the Colorado River. In actuality, a lot of people knew it--just not many with the Sierra Club. In fact, more people rafted through Glen Canyon a year than did through the Grand Canyon. C. Gregory Crampton wrote ten books about Glen Canyon before its demise, and liked to joke that THIS book should have been called "The Place the Sierra Club Didn't Know."
Which would have been more correct.
All that said, this book is a valuable historical document--for its role in the Glen Canyon controversy, and for its role in this century's environmental movement.
But it's not that good of a book. The photos are below average: many have a grainy, low quality-feel to them, and most of them are of very small things, and fail to give the true scope and grandeur of what Glen Canyon was. They are not Eliot Porter's best work, and some of the photos aren't even of Glen Canyon, but of other red rock from other places in Utah. (That's true, believe it or not, and it's well-documented.)
The quotes that accompany the photos are all right, but they're not amazing, they won't make you jump up.
A far, far better book featuring photos of Glen Canyon is Eleanor Inskip's "The Colorado River Through Glen Canyon: Before Lake Powell." Check it out.
And a far, far better collection of Eiliot Porter's is "Eliot Porter's Southwest." It's full of gorgeous black and white images from all over the Interior West.

A visual rhapsody.......2003-06-06

I got a copy of Eliot Porter's Glen Canyon book after reading Edward Abbey's "Desert Solitaire," a chapter of which is devoted to a downriver rafting trip along this stretch of the Colorado River just before the dam was built. While Abbey's descriptions are vivid, I wanted to see with my own eyes what he was describing. And Porter's camera is the closest you can get to doing that today.

His pictures are, of course, not the real thing, but they are about as breathtaking as photography can be. The colors, textures, reflections, and the play of light and shadow are wonderful, and each photograph is distinctly different. His own description of the canyon's display of color and light in the introductory essay "The Living Canyon" give an instructive insight into the eye of the photographer. His awareness of what he is looking at and his ways of choosing to look help the reader to see even more in the 80 photographs that follow.

While some of the photographs capture the monumental scale of the canyon walls and formations, many focus on the myriad surfaces that are revealed to the eye: erosion patterns, lichen, rippling water flow, the dark streaking mineral stains extending from seeps, the rough texture of weathered sandstone in glancing sunlight, smooth river stones, the layered stripes of exposed sediment, the trickling spread of water falling from overhead springs, the hanging tapestry coloration of the walls, whorled and striated rock, dry sand. There are also photographs of plants: moonflower, maidenhair fern, willow, tamarisk, redbud, columbine, cane. Above all, there is the rich array of colors, capturing a great variety of moods and attitudes.

Porter was recognized for his photography of birds, and while there are no birds visible in these photographs, his introductory essay makes mention of them, and when looked at with that awareness, many of the pictures also seem to capture a sense of "air space" for flight. Before turning to photography, Porter was a Harvard professor of biochemistry and bacteriology, and it's interesting to see the somewhat dispassionate eye of the scientist in the way he uses the camera. While the story of Glen Canyon may induce sorrow or anger, the photographs are strong for their lack of sentimentality.

The pictures also excite a curiosity about the geology of the river, and the book concludes with a short essay describing how the canyon walls reveal the geological ages that have gone into forming this part of the earth, going back millions of years. The book also includes a catalog of all the plants and animals that inhabited Glen Canyon before its inundation. Altogether, with its quotes from other writers, including Loren Eiseley, Joseph Wood Krutch, Wallace Stegner, and members of John Wesley Powell's expedition in the 19th century, this book is a fitting record of a great lost national treasure.

A heartbreakingly beautiful book.......2002-11-13

These photographs are just about all that is left of Glen Canyon. After the Sierra Club and other environmentalists had lost the battle to prevent the Glen Canyon River Dam from being built, Eliot Porter took this extraordinary series of photographs to memorialize the gorgeous area that has been lost forever. Few people at the time knew much about the Canyon. It was too remote, too difficult to get to. Although it was one of the areas that John Wesley Powell found most beautiful in his first expedition down the Green and Colorado Rivers, no access roads or paths were ever built to make it possible for many people to view the areas firsthand. As a result, very few people knew precisely what we were about to lose.

The tragedy is that these areas are really, truly are gone. Even if the Glen Canyon River Dam were magically removed, many of the areas viewed in these gorgeous photographs have already been silted up. The Green and Colorado Rivers carry extreme quantities of minerals, and when the dam stops the flow to form a reservoir, they tend to drop to the bottom. All dams have a limited life. They don't last for as long as one might imagine. Basically, they create a new landmass behind them over the course of a century or so. Many of the spots photographed in these pictures are now solid earth.

One would hope that such beautiful photographs as these, photos that create tremendous longing for what we have already lost, would make us more concerned to preserve what is left. But with the current presidency even today as I write this review opening the national parks to snowmobiles and with people speculating that there will be new attempts to open arctic areas in Alaska to oil exploration, we can't assume that in the least. These photographs may end up being emblematic of all endangered areas, of the ongoing fragility of all of nature.

Oversized Paperback Rivals Original Sierra Club Hardback.......2000-08-13

I was expecting a reprint similar to the small-sized Ballantine issue of the late 1960s. I was surprised to receive a book almost as large as the original Sierra Club hardback! The color in several of the photographs is even better than in the original (and difficult to find/very expensive) book, thanks in part to the cooperation of the museum which received Porter's works as a bequest.

Book Description

Long after their eradication from almost all parts of the US, wolves still evoke a primal response, firing the imagination with admiration, awe, and dread. Efforts to restore them to Yellowstone, North Carolina, and elsewhere have provoked heated public debate and met with only mixed success. Scientists and policymakers are debating the merits of returning the wolf to the northeastern US, where the forests of northern New England and upstate New York may provide the range and resources necessary to support them. This book brings together four thoughtful and literate observers of the natural world to reflect on the implications and potential of such an effort.

Bill McKibben, author of The End of Nature, encourages a skeptical look at our own motivations in this restorative effort, even as he argues that the psychological and spiritual benefits to humans would be at least as great as the ecological benefits of restoration. John Theberge, a scientist with years of experience in tracking the Canadian wolf population, notes that issues of restoration and "return" are far more complex from a biological and ecological point of view than much of the debate would suggest. Kristin DeBoer, director of the wolf restoration project of the environmental group RESTORE: The North Woods, reviews the state of the political debates, while also offering a personal account of her own motivations and goals in this work. Finally, novelist and nature writer Rick Bass brings the experiences of his home state of Montana to bear on the debate in the northeast.

Helping wolves.......2002-02-05

I believe this is a cause for restoration. This book made me believe that the wolf should be released in to the Adriondack mountians. It also had me believing that the ecosystem needs the wolves to survive. I was especially fascinated by Kristen Deboer's idea of creating corridors between parks in Canada ans the northeast, to help creat migratrion routes for animals.

The Return of the Wolf is an eye-opener as it gives four very distinct and honest evaluations of the possibility of our northeastern forest communities welcoming the timber wolf back to it's native haunts. Let us not confuse the eastern coyote which has hybridized with the eastern wolf as the as the easts top canid predator.....The wolf, just as in Yellowstone and Minnesota is the true predator of the moose , Caribou Elk and Beaver. The coyote, even if hybridized with wolf genes is still not a large enough creature(maximum of 70 pounds whereas the true timber wolf can be 100-150 pounds)to bring down the northeasts growing moose population and hopefully one day a restored caribou herd. Let the voice of Rick Bass,Kristen DeBoer and Bill McKibben weigh heavy.......let us set aside the lands, educate the "Little Red Riding Hood" believers and politic effectively with the state house representatives who tend to buckle to the pressure of corporations who favor short term extraction versus long term sustainability. Give the wolves the chance to push the coyotes to their rightful "fringe" of the forest allowing the true timber wolf and restored(hopefully) Cougar to stand atop the food chain as top predators of the land. Our forests have returned after 400 years of being chopped and burned.Let us stop the shopping malls and second home developments from destroying our wonderful open lands.Let the land be restored to it's glory and allow the current residents of the backwoods to continue their sustainable forestry and wsoodcraft busines while reaping some benefits from a contrulled and managed Ecotourism. What a great thing for us to have the pomeans and will to return and restore our woodlands in the most populated part of the U.S. to their former majesty. We can be a model for the conservative western United States and the emerging 3rd world countries to emulate......The Return of the Wolf speaks of all of these things and more........Fantastic writing! Rivals Charles Little storytelling in the "Dying of the trees". Please pass on to a friend.......Let the restoration of the north woods begin!
