A New Nonisothermal Ion-Exchange Method for Enrichment of Solutions.

A new dual temperature ion-exchange method for concentration and separation of solutes, the “swinging wave” method, was described. The method can be used for the reactant-free enrichment of solutions in microcomponents. The effectiveness of the method applied to the enrichment of bromides in sea water on a highly basic anion-exchange resin was demonstrated, and technological characteristics of this process were studied using computer simulation and experimental studies.
