摘要
吐温60水溶液在无机盐存在下能分成液-固两相。本文研究了水溶性螯合剂偶氮胂Ⅲ、XO在两相间的分配。讨论了用XO作萃取剂,Zr(Ⅳ)、Bi(Ⅲ)、Cu(Ⅱ)、Sc(Ⅲ)在吐温60固相中的萃取行为。实现了Zr(Ⅳ)-Sc(Ⅲ)、Zr(Ⅳ)-Cu(Ⅱ)的定量分离,初步探讨了吐溫60相的萃取机理。
The aqueous solution of Tween 60 can separate into liquid and solid phases. The separation conditions were established. The distribution of water-soluble ligands arsenazo Ⅲ and XO between the two phases in this system was examined. The extraction behaviour of Zr(Ⅳ). Bi(Ⅲ), Cu(Ⅱ) and Sc(Ⅲ) with XO as extractant was discussed. The quantitative extractiion separation of Zr(Ⅳ)-Sc(Ⅲ) and Zr(Ⅳ)-Cu(Ⅱ) was carried out. The extraction mechanism for Tween 60 phase was studied also.
