The extraction of U(VI) with HCBMPPT[4-(2chloro)benzoyl-2
4-dihydro-5-methyl- 2-phenyl-3H- pyrazol-3-thione] from nitric acid solution in toluene was studied. The distribution ratio of U(VI) increases with the increasing pH of the aqueous phase. Meanwhile when the concentration of HCBMPPT increases
the distribution ratio of U(VI) increases rapidly. The chemical composition of extracted complex and the mechanism of the extraction reac-tion were discussed.
