Book excerpt: Recent years have seen an expansion in speciality uses of activated carbons including medicine, filtration, and the purification of liquids and gaseous media. Much of current research and information surrounding the nature and use of activated carbon is scattered throughout various literature, which has created the need for an up-to-date comprehensive and integrated review reference. In this book, special attention is paid to porosities in all forms of carbon, and to the modern-day materials which use activated carbons - including fibres, clothes, felts and monoliths. In addition, the use of activated carbon in its granular and powder forms to facilitate usage in liquid and gaseous media is explored. Activated Carbon will make essential reading for Material Scientists, Chemists and Engineers in academia and industry. - Characterization of porosity - The surface chemistry of the carbons - Methods of activation and mechanisms of adsorptio - Computer modelling of structure and porosity within carbons - Modern instrumental analytical methods

This book was released on 2021-11-18 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: Our intention in publishing this book was to discuss and interpret all of the major issues in the chemical and environmental science disciplines, because this book covers such a broad range of chemical and environmental science research area. Rather, we have selected the themes and challenges, briefly defined them and demonstrated how they connect, clarified the terminology, and indicated where further research may be accessed. We hope that the result is an excellent introduction to 'chemical and environmental science. It is primarily aimed towards researchers in chemical science and related fields, but it should be accessible to new researchers as well. We have explored into more depth on issues that have received little attention elsewhere. There are several useful sources for topics such as chemical science, environmental science, nanotechnology, ionic liquids, solid waste management, photodegradation, Nanomaterial, adsorption of hazardous metals, and conducting polymers. However we attempted to provide up-to-current knowledge, we are well aware that books may soon go out of date if they seek to provide too much detail, so we concentrated on basic concepts that should not go out of fashion too quickly. Our book differs somewhat from other texts in the chemical and environmental sciences in its concentration. We have focused on ideas and theories because we feel that a solid grasp of them will be more useful in the long run than specifics of present systems, services, and approaches. We've also highlighted the dimension since we feel it's critical to understand where the discipline and its components originated from and why some things are the way they are. This approach is based on the research, with several references provided at the end of each chapter for convenience. Our intention is that the content of this book will be sufficient to provide a fundamental knowledge of the entire field, and that readers will refer to the references for more information and examples of the parts of which they are most interested. The conclusion words and captions, as well as the important references, at the conclusion of each chapter are intended to present the main points in a factual way.

Book Synopsis Synthesis and Characterization of Chemically Treated Activated Carbons for Adsorption of Trace Contaminants by : Christian Lincoln Mangun
Download or read book Synthesis and Characterization of Chemically Treated Activated Carbons for Adsorption of Trace Contaminants written by Christian Lincoln Mangun and published by . This book was released on 1997 with total page 314 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the undesirable features of the modern day world is widespread contamination associated with the release of a large number of chemicals into the environment. In recent years there has been a tremendous amount of work done to quantify the harmful effect of these trace contaminants. Society's growing concern has led many governments to establish stricter standards for clean air and water, many of them in the ppb range. This necessitates the development of greatly improved methods for controlling the release of toxic contaminants and on designing new materials tailored to selectively remove a wide range of contaminants and permit for recovery and reuse. One technology which is extremely attractive for this purpose is the use of dry adsorbents such as activated carbons. Activated carbons have been used for many years for both air and water purification through a physical adsorption process in the micropores. Activated carbon granules (ACG's) have been the industry standard for many years. They are used as adsorbents to purify polluted waste streams because of their low cost and because they have been determined to be the best available technology for removal of many contaminants. However, the ACG's suffer from a number of drawbacks including poor selectivity, slow kinetics, the need for expensive containment systems, less than 100% working capacity, and costly reactivation. Perhaps the most serious problem is the absence of a comprehensive understanding as to the effect of pore size and chemistry on the adsorption properties. Such knowledge would allow one to tailor activated carbons for control of specific contaminants. There is a definite need for the development of improved materials designed specifically for a wide range of environmental problems.

Book Synopsis Factors Affecting the Removal of Ammonia from Air on Carbonaceous Materials by : Camille Petit
Download or read book Factors Affecting the Removal of Ammonia from Air on Carbonaceous Materials written by Camille Petit and published by Springer Science & Business Media. This book was released on 2012-03-07 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: Air pollution related to the release of industrial toxic gases, represents one of the main concerns of our modern world owing to its detrimental effect on the environment. To tackle this growing issue, efficient ways to reduce/control the release of pollutants are required. Adsorption of gases on porous materials appears as a potential solution. However, the physisorption of small molecules of gases such as ammonia is limited at ambient conditions. For their removal, adsorbents providing strong adsorption forces must be used/developed. In this study, new carbon-based materials are prepared and tested for ammonia adsorption at ambient conditions. Characterization of the adsorbents’ texture and surface chemistry is performed before and after exposure to ammonia to identify the features responsible for high adsorption capacity and for controlling the mechanisms of retention. The characterization techniques include: nitrogen adsorption, thermal analysis, potentiometric titration, FT-IR spectroscopy, X-ray diffraction, Energy Dispersive X-ray spectroscopy, X-ray photoelectron spectroscopy and Electron Microscopy. The results obtained indicate that ammonia removal is governed by the adsorbent’s surface chemistry. On the contrary, porosity (and thus physisorption) plays a secondary role in this process, unless strong dispersive forces are provided by the adsorbent. The surface chemistry features responsible for the enhanced ammonia adsorption include the presence of oxygen-(carboxyl, hydroxyl, epoxy) and sulfur- (sulfonic) containing groups. Metallic species improve the breakthrough capacity as well as they lead to the formation of Lewis acid-base interactions, hydrogen-bonding or complexation. In addition to the latter three mechanisms, ammonia is retained on the adsorbent surface via Brønsted acid-base interactions or via specific reactions with the adsorbent’s functionalities leading to the incorporation of ammonia into the adsorbent’s matrix. Another mechanism involves dissolution of ammonia in water when moisture is present in the system. Even though this process increases the breakthrough capacity of a material, it provides rather weak retention forces since ammonia dissolved in water is easily desorbed from the adsorbent’s surface.

This book was released on 2004-01-01 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many water treatment plants need to remove objectionable trace organic compounds, and activated carbon adsorption is often the best available technology. Utilities face the challenge of having to choose from a large variety of activated carbons, and iodine number or BET surface area values are often utilized in the selection process. Although neither parameter correlates well with adsorption capacities, alternative activated carbon selection criteria based on fundamental adsorbent and adsorbate properties are lacking to date. The first objective of this research was to systematically evaluate the effects of activated carbon pore structure and surface chemistry on the adsorption of two common drinking water contaminants: the relatively polar fuel oxygenate methyl tertiary-butyl ether (MTBE) and the relatively nonpolar solvent trichloroethene (TCE). The second objective was to develop simple descriptors of activated carbon characteristics that facilitate the selection of suitable adsorbents for the removal of organic contaminants from drinking water.Originally published by AwwaRF for its subscribers in 2003 This publication can also be purchased and downloaded via Pay Per View on Water Intelligence Online - click on the Pay Per View icon below

Download or read book Interface Science in Drinking Water Treatment written by Gayle Newcombe and published by Academic Press. This book was released on 2006-09-06 with total page 377 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is difficult to imagine anything more important to the human population than safe drinking water. Lack of clean drinking water is still the major cause of illness and death in young children in developing countries. In more fortunate communities, where water treatment is practiced, the primary aim of water authorities is to provide water that is free from pathogens and toxins. Most countries now have water quality regulations, or guidelines, which are driving water authorities to produce purer water, with the minimum of contamination from natural or man-made origin. At the same time, consumers are demanding that chemicals added during the treatment of drinking water be kept to a minimum. As a consequence, conventional clarification methods are being challenged to comply with the new regulations and restrictions and our understanding of the mechanisms involved is being tested as never before. Interface Science in Drinking Water Treatment contains a rigorous review of water treatment practices from a fundamental viewpoint. The book includes material from leading experts in the field of water treatment, reviewing their specific fields of expertise against a background of colloid and surface chemistry, and examines each step of the journey from source to consumer tap. It therefore permits the reader to develop a deep understanding of the complex processes taking place and of the necessary treatments which are vital for the provision of safe and palatable drinking water. The book is aimed at researchers, educators and practitioners in science and engineering, particularly those involved in water treatment and colloidal chemistry. - Covers all existing water treatment processes, approached from a fundamental surface and colloid science viewpoint - Unique collection of R&D authors, all experts in water treatment processes - Comprehensive review of water treatment with a complete list of references
