Abstract: The syncrgistic extraction of uranium (V1) from nitric acid aqucons solution with a mixture of trisu-buty! phosphate (TBP) pnd petroleusn sulfoxides(PSO1 in benzene was studied. Tt has been found that the maximum synergistic extraction effect oceurs where the molar ratio of PSO to TBP is one to two. The composition of the complex of synergistic extraction is UO2(NO3)2.TBP PSO. The formation constant of the complex KTP=57.44.
