| 摘 要： | 研究了PhSO(CH2)nSOPh(n=2,3,4,6)－三氯甲烷体系从硝酸介质中萃取铀的行为。n=2的双亚砜在萃取时出现三相，n=3,4,6的三种双亚砜对铀的萃取规律类似于TBP，萃取性能略优于TBP。铀的溶剂化数均为1。

| Abstract: | The extraction of dioxouranium(Ⅵ) from nitric acid solution byPhSO(CH2)nSOPh (n=2，3，4，6)-trichloromethane was studied. When the disulfoxide was PhSO(CH2)2SOPh， the third phase formed. The extraction laws of dioxouranium(Ⅵ) by the disulfoxides (n=3，4，6) were similar to that by tributyl-phosphate(TBP). Their extracting ability was slightly better than that of TBP. |
