Electrodialytic Recovery of Desorbing Agent from Eluate Containing Sea-Water Uranium

Studies on the Extraction of Rare Elements from Sea Water (Part 4)

Abstract

Uranium was adsorbed from sea water, and then desorbed by the aqueous solution of alkali carbonate. The resulting solution was treated by electrodialysis with a combi nation of univalent selective anion exchange membrane and either selective or non -selective cation exchange membrane.With this process, it was found possible to selectively remove the alkali carbonate fr om the system by retaining the uranium in the solution.
