    摘要:

    以聚偏氟乙烯膜(PVDF)為支撐體，煤油為膜溶劑，三正辛胺為流動載體，研究分散支撐液膜體系中金屬Au(Ⅲ)的傳輸行為；考察料液相酸度、分散相膜溶液與解析液體積比、解析相中KCN濃度以及不同的解析劑對Au(Ⅲ)傳輸?shù)挠绊?。結果表明，當料液相鹽酸濃度為2.0 mol/L, 分散相中膜溶液與解析液體積比為40:20, 用KCN作解析劑，KCN濃度為0.5 mol/L時，該分散支撐液膜體系對金屬Au(Ⅲ)具有很好的傳輸作用

    Abstract:

    The transportation behavior of Au(III) through a dispersion supported liquid membrane (DSLM) consisting of tri-n-octylamine in kerosene, supported on the polyvinylidene fluoride membrane (PVDF), was studied. The effects of HCl concentrations in the feed phase, volume ratio of liquid membrane phase to strip phase, and concentrations of KCN in the strip phase were also researched. The results show that gold ion can be transported effectively when the concentration of HCl in the feed phase is 2.0 mol/L, the volume ratio is 40:20, and the concentration of KCN in the strip phase is 0.5 mol/L
