以三正辛胺-SPAN 80-二甲苯乳状液膜迁移、分离Cd(Ⅱ)的研究

Study on transport and separation of Cd(Ⅱ)through the emulsion liquid membrane of tri-n-octylamine-SPAN 80-oxylene

研究了用三正辛胺-SPAN 80-二甲苯乳状液膜体系迁移Cd(Ⅱ)的行为,确定了完全、快速迁移 Cd(Ⅱ)的制乳及迁移条件。在此条件下,Cd(Ⅱ)与常见共生离子Zn^(2+)、Co(2+)、Ni^(2+)、Fe^(2+)、Mn^(2+)等可完全分离。本方法可用于分离及分析工作。

The transport behaviour of Cd (Ⅱ) through theemulsion liquid membrane system of tri-n-octylamine-SPAN 80-oxylene has been studied.The optimum ex-perimental conditions for transport of Cd(Ⅱ)with highefficiency and high speed were obtained.In this case,Cd(Ⅱ) can be completely separated from Zn^(2+),Co^(2+),Ni^(2+),Fe^(2+),Mn^(2+),etc.
