Abstract: A novel extractant. N, N'-diacylpiperazine, (DAPEZ). was synthesized and characterized for the first time. Its extraction property for U(VT) from aqueons nitric acid media has been studied. The effects of concentration of nitzic acid and extractant on the distribution ratio were examined and the extraction mechanism were discussed.
