【Abstract】 The seperation of lead using the emulsion liquid membrane system was studied.Kerosene was used as membrane solvent,span 80 was used as surfactant and paraffin was used as membrane reinforcer.The effect of emulsifing time and mixing time,the concentration of span 80 and paraffin, the ratio of water to milk and oil phase to internal phase,HCl concentration of external phase were discussed in detail.The optimum conditions were established.更多还原
