【摘要】 研究了铝()在乳状液膜分离体系中的迁移行为.确立了最佳迁移条件:制乳搅拌速度2400 r/min,制乳时间10 min,乳液与外相溶液混合时间15 min,乳水比0.4,磷酸三丁酯(TBP)浓度4.5%,span80和液体石蜡浓度均为7.9%,内相和外相HCl浓度分别为1.0 mol/L和3.0 mol/L.在此条件下,铝()的迁移率达90%以上.更多还原

【Abstract】 The transfer behavior of aluminium(Ⅲ) through the following emulsion liquid membrane system was studied.The optimum conditions established were as follow: The stirring speed for emulsification was 2 400 r/min,the emulsifing time was 10 min,the mixing time of the emulsion and external phase solution was 15 min,the ratio of emulsion to water was 0.4,the concentrations of tributylphosphate(TBP) was 4.5 %,span80 and paraffin were both 7.9 % and HCl in the internal and external phases were 1.0 mol/L and 3.0 mol/L respectively.Under the conditions,the transfer of aluminium(Ⅲ) was > 90 %.更多还原
