发现6种双亚砜在各实验条件下对铀（Ⅵ）、钍（Ⅳ）的萃取及分离性能均优于TBP。还初步探讨了双亚砜类萃取剂的结构与性能的关系。

Abstract

The extraction of U(Ⅵ) and Th(Ⅳ) from nitric acid media by disulfoxides RSO(CH2)OR(n=4

6; R=CH3(CH2)2CH2-

CH3CH(CH3)CH2CH2-

CH3(CH2)3CH(C2H5)CH2-) was studied. The extraction laws for U(Ⅵ) and Th(Ⅳ) by disulfoxides are similar to that by tributylphosphate(TBP)

but their extracting and separating ability is superior to that of TBP. The relations between the structure of disulfoxides and their extracting and separating ability are briefly discussed.
