Abstract

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)
