Extraction behavior of N, N'-didecanoylpiperazine (DDPEZ) for U(VI) in a series of solvents from aqueous nitric acid media was investigated for the first time. The dependence of distribution ratios on the concentration of aqueous nitric acid, extractant and temperature has been discussed. The increasing sequence of extractive ability of DDPEZ is given: chloroform, carbon tetrachloride, dimethylbenzene, toluene, benzene.
