摘要

研究了N-（2-乙基）己基己内酰胺（EHCLA）-三甲苯从硝酸介质中萃取铀、钍。EHCLA对这两种元素的萃取规律类似于TBP。用斜率法求得铀、钍的溶剂化数均为2

硝酸为1。还就温度对于萃取的影响和铀、钍的反萃以及三相的形成进行了研究

计算了萃取平衡常数和铀、钍的△H值。初步探讨了萃取的机理。

Abstract

The extraction of uranium （Ⅵ）

thorium （ Ⅳ） and nitric acid as a function of aqueous HNO3 concentration

extractant concentration and temperature is studied with N-（2-ethyl-hexyl） caprolactam. The extracted species and enthalpy of extraction reaction are evaluated . The third phase formation in extraction of U（ Ⅵ）is also studied. In addition

back extraction behavior of U（Ⅵ）and Th（Ⅳ）from organic phase is tested . The results obtained are compared with those obtained by using TBP at the same experimental conditions.
