Chemists in disciplines ranging from solid-state physics to electrochemistry and biology explain the role of ion-transfer kinetics in their particular field and in applications to energy conservation, biosensing, photography, medicine, and a wide range of other areas. Includes detailed enough instruction in the experimental methodology that the reader should be able to test the principles experimentally, and even to write computer programs to simulate ion-transfer properties of hypothetical materials incorporated into equally hypothetical products, presumably for hypothetical customers.

An elementary act of charge transfer determines a variety of phenomena in physics, chemistry and biology. The study of charge transfer processes has developed together with general progress in theoretical physics and in fast high resolution spectroscopy, so that research deals now with a broad class of systems, materials and environmental conditions. The specific topics covered are: (1) the environment and reactant-environment interaction at bulk and interfaces; (2) the elementary act of electron and proton transfer; homogeneous and heterogeneous processes; (3) processes of ion and heavy group transfer; ion transport in complex systems; (4) artificially and naturally organized charge transfer in physics, chemistry and biology, technological applications (molecular electronics, sensors, modified electrodes, membrane transport).

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.

The investigation of the elementary reactions of reactive intermediate species began about half a centruy ago with the advent of free radical kinetics as an active area of chemical research. In spite of the relatively greater ease of detection of a species carrying an electrical charge, and the fact that organic chemists had for decades postulated mechanisms involving ionic intermediates, the systematic study of the elementary reactions of ions was delayed for more than twenty years after the first beginnings of free radical kinetics. Even at this writing, in 1978, the word "kinetics" is considered by many chemists to be synomomous with "kinetics of neutral species". Yet in spite of the relatively late start and separation from the mainstream of kinetics, the field of ion physics and chemistry is fluorishing, and growing at an ever faster pace. Instrumentalists devise ever more sophisticated apparatuses with capabilities of delving into nearly every aspect of the interactions between ions and molecules. Even satellites orbiting the earth are now being used effectively to determine rate coefficients of ionospheric ion-neutral reactions, some of which can not as yet be measured in the laboratory.

Adsorption, Ion Exchange and Catalysis is essentially a mixture of environmental science and chemical reactor engineering. More specifically, three important heterogeneous processes, namely, adsorption, ion exchange and catalysis, are analysed, from fundamental kinetics to reactor design with emphasis on their environmental applications. In Chapter 1, the subject of air and water pollution is dealt with. Data about pollutants and emission sources are given and the treatment methods are shortly presented. In Chapter 2, the very basics and historical development of adsorption, ion exchange and catalysis are presented as well as their environmental applications. Chapter 3 is devoted to heterogeneous processes and reactor analysis. All types of reactors are described in depth and reactor modelling, hydraulics and mass/heat transfer phenomena are examined for each type of reactor. Chapters 4 and 5 are dedicated to adsorption & ion exchange and catalysis, respectively. The basic principles are presented including kinetics, equilibrium, mass/heat transfer phenomena as well as the analytical solutions of the reactor models presented in Chapter 3. In the sixth chapter, the subject of scale up is approached. The two Annexes at the end of the book contain physical properties of substances of environmental interest as well as unit conversion tables. Finally, nearly all the examples contained are based on real experimental data found in literature with environmental interest. Most of the examples consider all aspects of operation design – kinetics, hydraulics and mass transfer.* Provides basic knowledge of major environmental problems and connects them to chemical engineering
