Its extraction property for U(VI) from aqueous nitric acid media has been studied. The effects of concentration of nitric acid and extractant on the distribution ratio were examined and the extraction mechanism were discussed.展开更多
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 concentratio...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.展开更多
