摘要

用放射性示踪法研究了TBP -苯体系对铀和铅、铋的萃取分离。实验结果表明

在 6mol LHNO3 介质中用TBP -苯作为萃取剂可使铀和铅、铋达到定量分离。阴离子交换法对铀进一步纯化后

利用分子电镀法制得厚度为 50 0 μg cm2 的2 3 3 U同位素靶

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.
