摘要

本文研究了4-邻氯苯甲酰基-2

4-二氢-5-甲基-2-苯基-3H-吡唑硫酮-3（HCBMPPT）与中性萃取剂磷酸三丁酯（TBP）的甲苯溶液从硝酸介质中对铀（VI）的协同萃取。实验结果表明

其萃取分配比随萃取剂浓度、协萃剂浓度、盐析剂浓度及pH值的升高而增大。同时

对萃合物的化学组成及萃取机理进行了分析和讨论。

Abstract

The synergistic extraction of U(VI) with HCBMPPT[4-(2-chloro)benzoyl-2

4-dihydro-5-methyl-2-phenyl-3H-pyrazol-3-thione] and TBP in toluene from nitric acid solution was studied. The result shows that the distribution ratio of U(VI) increases rapidly when the concentrations of HCBMPPT

TBP and the salting-out agent increase. Meanwhile

with the increasing of the aqueous phase pH

the distribution ratio of U(VI) also increases. The chemical composition of the synergistic extracted complexes and the mechanism of the synergistic extraction reaction were also discussed.
