Synergistic Extraction of U(VI) With HMBMPPT and TBP in Chloroform

Chen Jie

Abstract

The synergistic extraction of U(Ⅵ) from nitric acid solution with HMBMPPT \[4-(4-methoxy)-benzoyl-2,4-dihydro-5-methyl-2-phenyl-3H-pyrazol-3-thione\] and TBP (tributyl phosphate) in chloroform is studied including influences of pH, the concentrations of HMBMPPT and TBP on the distribution ratio. The synergistic extracted complexes are deduced as UO_2NO_3·MBMPPT·TBP and UO_2(MBMPPT)_2·TBP.
