摘要

研究了Ｎ．Ｎ．Ｎ．Ｎ－四丁基丁二酰胺（ＴＢＳＡ）从硝酸介质中萃取Ｔｈ（Ⅳ）的机理，得出了萃合物的结构为Ｔｈ（ＮＯ３）４．ＴＢＳＡ，分析ＴＨＮＯ３、Ｔｈ４＋、ＴＢＳＡ的浓度及温度对Ｔｈ４＋分配比的影响，并计算出萃取反应的表观平衡常数及热力学函数。

Abstract

The extraction mechanism of Th4+ with TBSA from the nitric acid medium has been studied by investigating the influences of[HNO3]

[TBSA]

[Th4+] and temperature upon the distribution ratio D of Th4+. The composition of extracted species is TI（NO3）4.TBSA.
