Abstract
PURPOSE: To enhance a enrichment ratio of uranium without decomposing components of a desorbing liquid, in desorbing and enriching uranium from an uranium adsorbing agent by the desorbing liquid, by a method wherein the desorbing liquid is preliminarily treated with a strongly basic anion exchange resin and then with a weakly acidic cation exchange resin.
CONSTITUTION: A minute amount of uranium contained in sea water is adsorbed with an adsorbing agent such as titanium dioxide for enrichment and the adsorbed uranium is desorbed by a desorbing liquid such as a carbonate solution or a bicarbonate solution. The obtained uranium-containing liquid 1 is passed through an anion exchange column 4 packed with a strongly basic anion exchange resin to adsorb uranium with the resin and the uranium-free desorbing liquid is recovered as a regenerated desorbing liquid 6. Next, an eluting solution 3 containing NaCl and HCl is passed through said column 4 to elute uranium, carbonate ion or the like in said resin and, after pH of an eluate is adjusted to 4 in a pH adjusting tank 7, it is passed through a weakly acidic cation exchange resin column 12 packed with an acrylic resin or the like to adsorb uranium contained therein by said resin and, thereafter, an eluting solution 11 comprising an aqueous hydrochloric acid is passed therethrough to elute uranium, thereby, recovering an enriched uranium-containing solution.
