Book Description
The declared objective of this book is to provide an introductory review of the various theoretical and practical aspects of adsorption by powders and porous solids with particular reference to materials of technological importance. The primary aim is to meet the needs of students and non-specialists who are new to surface science or who wish to use the advanced techniques now available for the determination of surface area, pore size and surface characterization. In addition, a critical account is given of recent work on the adsorptive properties of activated carbons, oxides, clays and zeolites. - Provides a comprehensive treatment of adsorption at both the gas/solid interface and the liquid/solid interface - Includes chapters dealing with experimental methodology and the interpretation of adsorption data obtained with porous oxides, carbons and zeolites - Techniques capture the importance of heterogeneous catalysis, chemical engineering and the production of pigments, cements, agrochemicals, and pharmaceuticals

Book Description
Pulp and paper production has increased globally and will continue to increase in the near future. Approximately 155 millions tons of wood pulp is produced worldwide and about 260 millions is projected for 2010. To cope with the increasing demand, an increase in production and improved environmental performance is needed as the industry is under constant pressure to reduce environmental emissions to air and water. This book gives updated information on environmentally benign approaches for pulp bleaching, which can help solve the problems associated with conventional bleaching technologies.* Main focus is on the environmentally friendly technologies that can help solve some of the problems associated with conventional bleaching technologies* Information given is up-to-date, authoritative and cites the experiences of many mills and pertinent research, which is of interest to those working in the industry or intending to do so* Covers in great depth all the aspects of various bleaching processes including environmental issues

Book Description
The book is about calorimetry and thermal analysis methods, alone or linked to other techniques, as applied to the characterization of catalysts, supports and adsorbents, and to the study of catalytic reactions in various domains: air and wastewater treatment, clean and renewable energies, refining of hydrocarbons, green chemistry, hydrogen production and storage. The book is intended to fill the gap between the basic thermodynamic and kinetics concepts acquired by students during their academic formation, and the use of experimental techniques such as thermal analysis and calorimetry to answer practical questions. Moreover, it supplies insights into the various thermal and calorimetric methods which can be employed in studies aimed at characterizing the physico-chemical properties of solid adsorbents, supports and catalysts, and the processes related to the adsorption desorption phenomena of the reactants and/or products of catalytic reactions. The book also covers the basic concepts for physico-chemical comprehension of the relevant phenomena. Thermodynamic and kinetic aspects of the catalytic reactions can be fruitfully investigated by means of thermal analysis and calorimetric methods, in order to better understand the sequence of the elemental steps in the catalysed reaction. So the fundamental theory behind the various thermal analysis and calorimetric techniques and methods also are illustrated.

Book Description
The subject matter of this book is not entirely new in that much has been written about the state of the interfacial chemistry in other textbooks. However, the authors have found that there is really a need for a book which can lead an investigator, a student, or a beginn er through the in-depth understanding and descriptions involved in the derivations and usage of the adsorption equations based on the unified concept of the Gibbs surface excess. The derivation of the original Gibbs equation for the liquid interface has been amplified with reformulations and criticisms. Attempts have been frequently made to relate the surface excess quantities with the thermodynamic properties of the physically defined interfacial phase. In the last two decades, useful applications of the Gibbs equations have been made for the study of adsorption at solid-liquid as weIl as liquid-gas interfaces formed in the presence of the multicomponent solutions in the bulk. These recent treatments become useful for the experimental studies of the adsorption of electrolytes and interfacial properties related to neutral and charged monolayers. The consistency of the experimental results with those to be expected from the theories of the electrical double layer needs careful examination. An attempt has been made to present in a single volume all these developments based on the unified concept of the Gibbs surface excess. The study of the adsorption from solution is of considerable importance in the field of biology and in many other branches of applied science.

Book Description
Adsorption From Solution discusses the significance of adsorption behavior in thermodynamic terms, with emphasis on the interplay between enthalpic and entropic contributions to the free energy. This book examines the role of simple models and of elementary thermodynamic and statistical mechanical arguments in relation to the concept of surface phase. Organized into 22 chapters, this book starts with an overview of the theoretical model for the solid/liquid interface. This text then proceeds with a discussion of the general thermodynamic treatment of adsorption from mixed solvents, which is designed to apply in situations where adsorbed species may be regarded as distinct from their bulk counterparts. Other chapters discuss the adsorption from solutions of various interfaces of liquid/gas, liquid/liquid, or liquid/solid. The final chapter deals with the roles of adsorption from solution in controlling other phenomena, such as liquid–liquid displacement, wetting, and the forces between colloidal particles. Physicists, chemists, and materials scientists will find this book extremely useful.

Book Description
Since the original publication of this book in 1992, the bleaching process has continued to attract the attention of researchers and the edible-oil industry. In this 2nd edition, the reader is directed to more modern techniques of analysis such as flame-atomic adsorption, graphite furnace atomic adsorption, and atomic emission spectrometry involving direct current plasma (DCP) and inductively coupled plasma (ICP). It also discusses the Freundlich Equation and reports on high-temperature water extraction, high- temperature oxidative aqueous regeneration, and extraction with supercritical CO2. Finally, various degumming methods improved over the past several decades are discussed - Second edition features the progress in the bleaching and purifying of fats and oils since the mid-1990s - Includes extensive details on the adsorptive purification of an oil prior to subsequent steps in the process, including refining and deodorization - Offers practical considerations for choosing membranes, filtration equipment, and other key economic consideratons

Book Description
Interface and colloid science is an important, though often under-valued, branch of science. It has applications and ramifications in domains as disparate as agriculture, mineral dressing, oil recovery, chemical industry, biotechnology, medical science, and many more. Proper application of interface and colloid science requires factual knowledge and insight into the many basic laws of physics and chemistry upon which it is based. Fundamentals of Interface and Colloid Science is the first book to cover this field in the depth neccessary to be a valuable reference and an excellent textbook.From the beginning to the end of the book, systems of growing complexity are treated gradually. The presentation is particularly suited to emphasize that interfaces are not autonomous phases. As a rule, interfacial properties can be varied only by changing the adjoining phases, so that the properties of these bulk phases must be understood first. The text also recognizes common principles behind a variety of phenomena, and helps the reader to understand them and to develop and improve processes. The systematic treatment of the material in the book makes this clear, and makes the text itself an important contribution to the field. - Systematic treatment of information - An excellent addition to volume I - Two chapters contributed by other experts in the field - Uses a deductive approach to increase the order of complexity - Written by a leading expert in the field - Two chapters contributed by other outstanding scientists - Uses a systematic and deductive approach - First comprehensive review of the topic
