These Conference Proceedings deal with the papers presented at the International Conference on Ion Exchange Processes (ION-EX '87) which was held at The North East Wales Institute of Higher Education, 13-16 April 1987. The camera-ready paper format was chosen so that delegates could receive their copy on arrival at the Conference. The Proceedings include reviews of traditional ion exchange processes, ion chromatography and synthesis of resins. In addition there are research papers dealing with inorganic ion analysis; organic acid and organic base analysis; the theory of ion exchange and novel developments; the industrial ion exchange procedures; and finally inorganic ion exchangers. The Proceedings should therefore be of interest to those who need to be brought up to date in the various aspects of processes which involve ion exchange and ion chromatography which are now accepted as important in analysis, separation processes and process control. In each of these areas there have been important developments which are herein described. As Editors we should like to express our thanks to the individual authors for preparing their manuscripts in the required format and to Haydn Hughes for his invaluable assistance in compiling these Proceedings.

These Conference Proceedings deal with the papers presented at the International Conference on Ion Exchange Processes (ION-EX '90) which was held at The North East Wales Institute of Higher Education, 9- 11 July 1990. The camera-ready paper format was chosen so that delegates could receive their copy on arrival at the Conference. The Proceedings include reviews of biological materials, inorganic ion exchangers, the nuclear industry, theoretical aspects and new advances. In addition, there are research papers dealing with industrial ion exchange procedures and new materials. The Proceedings should therefore be of interest to those who need to be brought up to date in the various aspects of processes which involve ion exchange and ion chromatography which are now accepted as important in analysis, separation processes and process control.

This book covers new systems in technology that have developed our knowledge of ion exchange. This book discusses ion exchange resins to enhance cell growth; anion exchange membrane; nanosystems in ion exchange and ion exchange in environmental applications. The ion exchange system is used in bionanotechnology, cosmetic industry and water treatment.

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

Comprehensive text provides sound understanding of the relevant factors in ion exchange and the theoretical tools needed to solve specific problems. Detailed coverage of ion exchangers, equilibria, kinetics, electrochemical properties, ion-exchanger membranes, much more. Each chapter contains helpful summary and references. Accessible to nonmathematical students. Introduction. 1962 edition.
