Book Description
A new method for improving the selectivity of activated carbons for adsorbing perchlorate has been developed. The technique involves alkylation of functional groups present on the activated carbon surface. The modified activated carbon typically have adsorption capacities 5-10 times that of the parent activated carbon. The technique is believed to mainly alkylate the oxygen surface groups rather than the nitrogen surface groups.

Book Description
The capital and regeneration costs of activated carbon and ion exchange media suggest that better process economics may be achieved with disposable sorbents for the treatment of metals-contaminated water and waste streams. An extensive literature search was conducted to identify potentially inexpensive sorbents that could be disposed, rather than regenerated, after use. The literature indicates that many materials with this potential are readily available, either as process by-products or in their natural form. The most promising sorbents identified in this literature search will be tested at bench scale with synthetic metal solutions.
Book Description
This is the second volume on adsorption using green adsorbents and is written by international contributors who are the leading experts in the adsorption field. Together with the first volume they show a typical selection of green materials used in wastewater treatment, with emphasis on industrial effluents. This second volume focuses on innovative materials. It presents hemp-based materials for metal removal, and the use of leaves for metal removal. It describes the biosorption of metals and metalloids on various materials and discusses the recent advances in cellulose-based adsorbents used in environmental purposes. Furthermore, activated carbons from food wastes, aerogels and bones, and municipal solid waste biochar as efficient materials for pollutant removal, respectively are reviewed as well as biosorption of dyes onto microbial biosorbents and the use of mushroom biomass to remove pollutants are looked at. The volume also includes detailed review of green adsorbents for removal of antibiotics, pesticides and endocrine disruptors and the use of pillared interlayered clays as innovative materials for pollutant removal. Finally, the use of green adsorbents for radioactive pollutant removal from natural water is discussed. The audience for this book includes students, environmentalists, engineers, water scientists, civil and industrial personnel who wish to specialize in adsorption technology. Academically, this book will be of use to students in chemical and environmental engineering who wish to learn about adsorption and its fundamentals. It has also been compiled for practicing engineers who wish to know about recent developments on adsorbent materials in order to promote further research toward improving and developing newer adsorbents and processes for the efficient removal of pollutants from industrial effluents. It is hoped that the book will serve as a readable and useful presentation not only for undergraduate and postgraduate students but also for the water scientists and engineers and as a convenient reference handbook in the form of numerous recent examples and appended information.

Book Description
Based on a symposium sponsored by the Environmental Division of the American Chemical Society, Perchlorate in the Environment is the first comprehensive book to address perchlorate as a potable water contaminant. The two main topics are: analytical chemistry (focusing on ion chromatography and electrospray ionization mass spectrometry), and treatment or remediation. Also included are topics such as ion exchange, phytoremediation, bacterial reduction of perchlorate, bioreactors, and in situ bioremediation. To provide complete coverage, background chapters on fundamental chemistry, toxicology, and reulatory issues are also included. The authors are environmental consultants, government researchers, industry experts, and university professors from a wide array of disciplines.

Book Description
Use of Adsorbents for the Removal of Pollutants from Wastewater describes the most commonly occurring industrial effluents, and presents direct means and methodologies for treating them. In addition to its excellent introduction to pollutants, this book contains all of the basics you need for understanding the characteristics and applications of adsorbent materials. With this book, you can choose from a wide variety of traditional and novel adsorbents, including alternative, relatively inexpensive adsorbents.

Book Description
Perchlorate contaminates waters in 15 US states that 15 million American could otherwise drink. Although, conventional granular activated carbon (GAC) has a very limited capacity for removing perchlorate, it was found that ammonia thermal tailoring could enhance its bed life.
