Web15 apr. 2024 · Ion exchangers are generally produced as either a gel structure or macroporous structure. Gels are typically less expensive to produce and are far more common. Gel resins are usually transparent and do not have distinct pores. The transport mechanism for gel type ion exchangers is by diffusion. WebAbstract. The review deals with the modern hypotheses concerning the physicochemical properties of ion-exchange resins and their effects in the interaction between resins and solvents and solutes, mainly electrolytes. The problems associated with the permeability of resins, the steric accessibility of the functional centres, and their screening ...
