Summary
The studies on sorbent regeneration by Donnan dialysis have been presented. Two kinds of anion exchange membranes were evaluated: microheterogenous, based on interpenetrating polymer network and homogenous prepared from modified homopolymer. The studies revealed that sodium chloride is the salt that forced borate transport more effectively than sodium sulfate does. Both membranes showed similar efficiency in borate transport. It was shown that the particle diffusion within resin particles was the limiting process parameter for regeneration of boron selective resins. (c) 2007 Elsevier Ltd. All rights reserved.
