CONCENTRATION OF URANIUM(VI) WITH A CHELATE-FORMING SORBENT

Abstract

The sorption properties of a modified sorbent based on a maleic anhydride-styrene copolymer with respect to uranium(VI) have been studied. The main quantitative characteristics of metal ion sorption are determined. A sorbent containing fragments of molon acid hydrazide for the selective extraction of uranium(VI) from solutions is proposed. The optimal sorption conditions were determined. The degree of extraction of uranium(VI) under optimal conditions exceeds 95%. A technique for the sorption-photometric determination of uranium(VI) in sea water has been developed.
