【Abstract】 The extraction and separation of uranium from lead and bismuth with TBP-benzene was studied by radiotracer technique. The experimental results demonstrated that using TBP-benzene as an extracting solvent in 6mol/L HNO 3 could quantitatively remove the impurities of lead and bismuth from uranium。After purification of uranium, 233 U isotopic target with thickness of 500μg/cm 2 was obtained by means of molecular electrodeposition.更多还原
