Abstract
Extraction studies of uranium(VI) and molybdenum(VI) with organophosph oric, phosphinic acid and its thiosubstituted derivatives have been ca rried out from 0.1-1.0M HCl solutions. The extracted species are propo sed to be UO2R2 and MoO2CIR on the basis of slope analysis for uranium (VI) and molybdenum(VI), respectively. The extraction efficiencies of PC-88A, Cyanex 272, Cyanex 301 and Cyanex 302 in the extraction of mol ybdenum(VI) and uranium(VI) are compared. Synergistic effects have bee n studied with binary mixtures of extractants. Separation of molybdenu m(VI) from uranium(VI) is feasible by Cyanex 301 from IM HCl, the sepa ration factor log beta being 2.3.
