摘　　要：报道了用乳状液膜法分离汞的研究。确立了最佳分离条件 :流动载体 TBP(磷酸三丁酯 )和表面活性剂 Span80的浓度均为 9% ,内相溶液 Na OH和外相溶液HCl的浓度分别为 0 .4mol/ L和 0 .0 2 mol/ L ,制乳时间和混合时间分别为 1 0 min和5min,乳水比和油内比分别为 0 .5和 0 .8。The separation of mercury using the emulsion liquid membrane system was studied. The optimum conditions were established. The concentrations of carrier TBP and surfactant Span 80 were both 9%. The concentrations of NaOH in internal phase and HCl in external phase were 0 4 mol/L and 0 02 mol/L, respectively. The emulsifing time and mixing time were 10 minutes and 5 minutes, respectively. The ratios of milk to water and oil phase to internal phase were 0.5 and 0.8, respectively.
