以三正辛胺-失水山梨糖醇单油酸酯-二甲苯乳状液膜迁移分离汞(Ⅱ)的研究

Study on Transport and Separation of Mercury (Ⅱ) Through the Emulsion Liquid Membrane of Tri-n-octylamine-SPAN 80-Oxylene

用三正辛胺-失水山梨糖醇单油酸酯-二甲苯乳状液膜体系研究了汞(Ⅱ)的迁移行为,确定了完全且快速迁移汞(Ⅱ)的制乳和迁移条件。汞(Ⅱ)可与常见离子Zn^(2+)、Cd^(2+)、Co^(2+)、Ni^(2+)、Cu^(2+)、Pb^(2+)、Mn^(2+)等得到满意的分离。

The transport behaviour of Hg(Ⅱ) through the emulsion liquid membrane system of tri-n-octy-lamine-SPAN 80-oxylene has been studied. The optimal experimental condition for transport of Hg(Ⅱ) with high efficiency and high speed was obtained. In this case , Hg(Ⅱ) can be separated in the solution containing Zn2+ ,Cd2+ .Fe2+ ,Co2+ ,Ni2+ ,Cu2+ ,Pb2+ ,Mn2+ ,etc. completely. This method is useful for separation and analysis works in theory or in practice.
