Ion Exchange Science And Technology

Proceedings of the NATO Advanced Study Institute on Ion Exchange: Science and Technology, Troía, Portugal, July 14-26, 1985

Ion-exchange Technology I: Theory and Materials describes the theoretical principles of ion-exchange processes. More specifically, this volume focuses on the synthesis, characterization, and modelling of ion-exchange materials and their associated kinetics and equilibria. This title is a highly valuable source not only to postgraduate students and researchers but also to industrial R&D specialists in chemistry, chemical, and biochemical technology as well as to engineers and industrialists.

The Principles of Ion Exchange Technology covers the fundamental properties of ion exchange resins and the chemical engineering principles of plant design to aid process and equipment evaluation, choice and design. This text is composed of 12 chapters and begins with a discussion of the equilibrium concept and the calculation of diffusion coefficients and mass transfer coefficients, as well as the rate constants in ion exchange. The succeeding chapters deal with the kinetics of ion exchange in solution and in resin beads. These topics are followed by reviews of axial mixing, flow abnormalities, design equations, fixed bed performance calculation, and multi-component ion exchange. The final chapters explore the choices of continuous and countercurrent design techniques and the practical procedures for packed beds. This book is of great value to chemical engineers.

Today, membranes and membrane processes are used as efficient tools for the separation of liquid mixtures or gases in the chemical and biomedical industry, in water desalination and wastewater purification. Despite the fact that various membrane processes, like reverse osmosis, are described in great detail in a number of books, processes involving ion-exchange membranes are only described in a fragmented way in scientific journals and patents; even though large industrial applications, like electrodialysis, have been around for over half a century. Therefore, this book is emphasizing on the most relevant aspects of ion-exchange membranes. This book provides a comprehensive overview of ion-exchange membrane separation processes covering the fundamentals as well as recent developments of the different products and processes and their applications. The audience for this book is heterogeneous, as it includes plant managers and process engineers as well as research scientists and graduate students. The separate chapters are based on different topics. The first chapter describes the relevant Electromembrane processes in a general overview. The second chapter explains thermodynamic and physicochemical fundamentals. The third chapter gives information about ion-exchange membrane preparation techniques, while the fourth and fifth chapter discusses the processes as unit operations giving examples for the design of specific plants. First work on the principles and applications of electrodialysis and related separation processes Presently no other comprehensive work that can serve as both reference work and text book is available Book is suited for teaching students and as source for detailed information

Fundamental study and industrial application of ion exchange membranes started over half a century ago. Through ongoing research and development, ion exchange membrane technology is now applied to many fields and contributes to the improvement of our standard of living. Ion Exchange Membranes, 2nd edition states the ion exchange membrane technology from the standpoint of fundamentals and applications. It discusses not only various phenomena exhibited by membranes but also their applications in many fields with economical evaluations. This second edition is updated and revised, featuring ten expanded chapters. New to this edition is a computer simulation program of ion-exchange membrane electrodialysis for water desalination that provides a guideline for designing, manufacturing and operating a practical-scale electrodialyzer. Meant to replace experiments, this program will be an important asset to those with time and monetary budgets.

Ion Exchange Materials: Properties and Applications fills a "two-dimensional" gap in books currently available on the subject. Firstly, there is a lack of modern comprehensive publications on the chemistry of ion exchange materials and on the relationships between their properties and practical applications. Secondly, there are few books on ion exchange chemistry that are targeted to industrial R&D specialists and research students who (i) do not work with ion exchange on a daily basis, (ii) need to develop competence in this area, and (iii) find it difficult to start studying the subject from primary scientific publications. The book bridges these gaps by describing classical and modern theoretical concepts, as well as practical approaches for using ion exchange materials. Ion exchange materials combine properties of homogeneous and heterogeneous materials. Besides being an interesting subject for investigation, they are essential in a wide variety of industrial technologies: in the chemical and biochemical industries, pharmacy, medicine, microelectronics, the nuclear industry, food production, waste treatment, and many other areas. Ion exchange is a powerful tool in chemical analysis and scientific research. The main focus in this book is on ion exchange polymers: ion exchange resins, chelating resins, imprinted (templated), and other functional polymers. It provides an in-depth study of ion exchange materials, suitable for postgraduate students and R&D industrial specialists in chemistry, chemical and biochemical technology. Comprehensively covers the subject Provides links between theoretical concepts, material properties, practical applications, and technical solutions Easy to understand - requires only ground knowledge of university-level chemistry and can be read without an in-depth knowledge of mathematics Supported with an interactive website

Ion Exchange Technology serves both as a reference and as a text book for technologists and engineers. While the present book is based mainly on ion exchange as practiced in the United States, the object was to produce a generally useful book which would deal with the fundamental problems, techniques, and operations of ion exchange such as mass transfer, equipment design, properties of ion exchange resins, and deionization. Also include are chapters on two types of applications—those that are used industrially on a large scale, and those which have not yet reached large-scale use but have impressive potentialities. In both the fundamental and applied chapters it was deemed necessary that the successful aspects of ion exchange operation be included. In addition, it was equally important to describe the problems and the inherent complexities encountered in the setting up of an ion exchange process. Wherever possible the economic factors were described realistically.
