Book excerpt: Ion exchanger resin fluid film mass transfer coefficients and the ionic diffusivities from which they are derived are often measured by use of ion exchange resin columns. Such tests, usually run dynamically using short resin beds, are often performed using relatively high (ppm) concentrations of ions to accurately measure output concentrations as a function of flow rate. The testing described herein was performed to determine fluid film ionic diffusivities for cationic concentrations typical of ultrapure water ({le}ppb levels) containing ppm levels of ammonia. Effective ionic diffusivities at these low ionic concentrations and high pHs were needed to complete a computer model (SIMIX) to be used in ion exchange simulations. SIMIX is a generalized multicomponent ion exchange model designed to simulate the removal of divalent cations from ultrapure water.

Book excerpt: While ion-exchange processes were originally used for the treatment of very dilute solutions, many applications for the treatment of concentrated solu tions have been developed in recent years. In these situations, the mass transfer bottlenecks are located in the~, rather than the liquid phase. Therefore, the development of quantitative models for ion-exchange kinetics requires knowledge about the conductance characteristics of ions and solvent in the solid phase. A useful approach towards this aim is the study of trans port characteristics of these species, and of their interactions in solid ion exchange membranes. Many different transport processes and related phenomena can be observed in membrane-solution systems, e.g., ion migration, electroosmosis, diffusion arid self-diffusion, osmosis, hydraulic flow, hyperfiltration (reverse osmosis) or ultrafiltration, streaming potential and streaming current, and membrane potentials (also called "membrane concentration potentials"). It is important to correlate all these phenomena so as to avoid a very large number of unnec essary measurements. Such correlation is often possible [Meares, 1976] since all these phenomena are determined by the ease of migration of the different species across the membrane. Important correlations have been made and summar ized even before high-capacity ion-exchange membranes became commercially available [Sollner, 1950, 197iJ.

Available in PDF, EPUB and Kindle. Book excerpt: Provides a comprehensive introduction to ion exchange for beginners and in-depth coverage of the latest advances for those already in the field As environmental and energy related regulations have grown, ion exchange has assumed a dominant role in offering solutions to many concurrent problems both in the developed and the developing world. Written by an internationally acknowledged leader in ion exchange research and innovation, Ion Exchange: in Environmental Processes is both a comprehensive introduction to the science behind ion exchange and an expert assessment of the latest ion exchange technologies. Its purpose is to provide a valuable reference and learning tool for virtually anyone working in ion exchange or interested in becoming involved in that incredibly fertile field. Written for beginners as well as those already working the in the field, Dr. SenGupta provides stepwise coverage, advancing from ion exchange fundamentals to trace ion exchange through the emerging area of hybrid ion exchange nanotechnology (or polymeric/inorganic ion exchangers). Other topics covered include ion exchange kinetics, sorption and desorption of metals and ligands, solid-phase and gas-phase ion exchange, and more. Connects state-of-the-art innovations in such a way as to help researchers and process scientists get a clear picture of how ion exchange fundamentals can lead to new applications Covers the design of selective or smart ion exchangers for targeted applications—an area of increasing importance—including solid and gas phase ion exchange processes Provides in-depth discussion on intraparticle diffusion controlled kinetics for selective ion exchange Features a chapter devoted to exciting developments in the areas of hybrid ion exchange nanotechnology or polymeric/inorganic ion exchangers Written for those just entering the field of ion exchange as well as those involved in developing the “next big thing” in ion exchange systems, Ion Exchange in Environmental Processes is a valuable resource for students, process engineers, and chemists working in an array of industries, including mining, microelectronics, pharmaceuticals, energy, and wastewater treatment, to name just a few.

Available in PDF, EPUB and Kindle. Book excerpt: Ion Exchange, 2nd Edition is a totally revised and updated version of the highly popular Monograph for Teachers, first published by The Royal Society of Chemistry in 1975. It covers the practical application of ion exchange and the synthesis of organic ion exchange resins, which have spanned nearly 60 years of development since the pioneering work of Adams and Holmes in 1935. This book covers the theory, development, and application in considerable detail and describes the history of development of ion exchange materials and the advances in their utilization in industrial processes. Key applications in such areas as water purification, hydrometallurgy, and chromatography are described and supported by chapters on the related scientific fundamentals governing equilibria and kinetics of ion exchange. Twenty-two experiments using inexpensive equipment are detailed, which not only complement a chapter dedicated to the characterization of organic exchangers, but also serve to illustrate several other pure and applied principles related to ion exchange phenomena. It is anticipated that the unique inclusion of experiments and the broad coverage of the whole text should appeal to a wide readership and offer particular relevance to practitioners in schools, colleges, and industry.
