Fractionation of multicomponent solutions by electrodialysis with bipolar membranes
Abstract The process of electrodialysis with bipolar membranes and the performance characteristics of plants that use this process are described. The first results of the laboratory tests of an electrodialysis plant with bipolar membranes are given; these results show that the salt wastes of nuclear power plants can be practically utilized with the manufacture of useful products (acids, alkalis, and boric acid) for the repeated use at the plant. The use of modified ion-exchange membranes and a two-compartment electrodialyzer design with bipolar membranes for the removal of ionic impurities from the solutions of acids and alkalis, in particular, for the production of pure boric acid, is proposed.
