Book Description
The absorption of uranium and sulfate from sulfate solutions by the anion exchange resin Amberlite IRA-400 in the chloride form has been studied using pure solutions. Strong bisulfate adsorption in addition to sulfate absorption was found to occur in acid solutions. Uranium adsorption was found to increase with uranium concentration and with pH, and to decrease with increasing sulfate concentration. Magnesium sulfate was found to retard uranium adsorption to a greater extent than sodium sulfate. Evidence was found which indicates that the uranium complex anion is of general form UO2(SO4)n2−2n.

Book Description
Volume 9 of this series continues in the tradition of its highly acclaimed predecessors, containing current knowledge and results in ion exchange. Presenting theoretical and applied information, this comprehensive reference provides authoritative, interdisciplinary coverage of contemporary topics such as kinetics and dynamics of the interaction of organic ions with various ion-exchange resins ... the application of ion-exchange techniques to the resolution of a spectrum of technical problems ... the influence of humic and fulvic acids on the composition of natural waters ... water sorption properties of ion exchangers ... and much more! The Ion Exchange and Solvent Extraction Series treats ion exchange and solvent extraction both as discrete topics and as a unified, multidisciplinary study -- presenting new insights for researchers in many chemical and related fields. The volumes in this now-classic series must be owned by biophysicists; biochemists; membrane researchers; radiochemists; electrochemists; analytical, physical, coordination, and environmentalists; and chemical engineers.

Book Description
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.
