摘要
研究了span80(失水山梨醇单油酸脂)-SDS(十二烷基磺酸钠)与span80-AOT(2-乙基己基琥珀酸酯磺酸钠)两种乳状液膜体系对锌(Ⅱ)分离效果的比较。分别讨论了液膜体系中表面活性剂和内相试剂浓度、乳水比和油内比对锌(Ⅱ)去除率的影响。试验了锌(Ⅱ)与共存组分的分离。
The separation of zinc （ Ⅱ ） by emulsion liquid membrane systems was studied. The systems of spanS0 （ sorbitan mo- nooleate）-SDS（ sodium dodecyl sulfate）and span80-AOT （AerosolOT, 2-ethylhexyl succinate sodium sulfate）were compared. The impact of concentration of surfactants on the removal rate for zinc ion and the reagent in internal phase, the ratio of milk to water and oil phase to internal phase have been discussed respectively. The separation of zinc ion from coexistence components was tested.
