摘要
乳状液膜分离技术已经在许多领域中应用,在液膜中加入流动载体,可促进物质的迁移.本文从萃取剂中筛选出来双硫腙,可作为铅、铜离子迁移的优良流动载体.用双硫腙-Span 80-甲苯的乳状液膜体系,在20～30min试验中,铅、铜的迁移率均接近100％,而在同样条件下,锌不迁移,因此,用该乳状液体系可分离铅、铜和锌.
The transport of lead( Ⅱ ), zinc( Ⅱ ) and copper( Ⅱ ) in dithizone-mediated emulsion liquid membrane system was studied. The transporting behavior of lead( Ⅱ ) in the liquid membrane system is reported in detail. Because of the selectivity of dithizone. the separating of lead ( Ⅱ ) from zinc( Ⅱ ), copper ( Ⅱ ) from zinc( Ⅱ ) can be completed by using this liquid membrane system.
