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
