摘要
本文研究了外水相ｐＨ值、流动载体浓度、表面活性剂浓度、内相解析酸浓度、水乳比、油内比等因素对二（２，４，４－三甲基戊基）单硫代膦酸（Ｃｙａｎｅｘ３０２）－上胺２０５－正庚烷乳状液 膜迁移Ｓｃ（Ⅲ）的影响。在一定条件下，Ｓｃ（Ⅲ）可以快速而完全地迁移，有可能实现Ｓｃ（Ⅲ）与Ｆｅ（Ⅲ）、Ｌｕ（Ⅲ）的分离。
The separation of Sc (Ⅲ), Fe (Ⅲ) and Lu (Ⅲ) by bis (2, 4, 4-trimethylpentyl) monothiophosphinic acid (Cyanex302)-N205-heptane emulsion liquid membrane (ELM) was studied. Effects of different factors on the transport of Sc(Ⅲ) by the ELM were investigated. Under certain conditions, Sc(Ⅲ) could be transported completely and quickly. The result also shows that it is possible to separate Sc(Ⅲ), Fe(Ⅲ) and Lu(Ⅲ) with Cyanex 302- N205-heptane emulsion liquid membrane.
