摘要: 用三正辛胺-SPAN80-二甲苯乳状液膜体系迁移Mo(Ⅵ)的研究表明,在合适的制乳和迁移条件下,Mo(Ⅵ)可以快速、完全地迁入内相,并能与Fe2+、Cu2+、Co2+、Ni2+、Zn2+、Cd2+、Mn2+等常见离子分离。

Abstract: The studies on the transport of Mo(Ⅵ) with the aid of the emulsion liquid membrane of tri-n-oetylamine-SPAN 80-oxylene indicate that Mo(Ⅵ) could be completely and rapidly transported under the optimum experimental conditions, during which many co-ions, such as Fe2+, Co2+, Ni2+, Cu2+, Zn2+, Cd2+, Mn2+ etc.could not be transported by this emulsion liquid membrane.So Mo (Ⅵ) can be separated from these ions satisfactorily.This is a useful separation method with a high efficiency and a high speed and can be used in theory and in practice.

Key words: Emulsion liquid membrane, Tri-n-octylamine, Transport, Separation, Mo(Ⅵ)
