摘要： 利用各种分离技术分离和富集金属离子,无论是在环境保护还是在湿法冶金方面都具有重要的意义.油包水型微乳状液因具有独特的物理化学性质,已越来越广泛地应用于金属离子的萃取分离上.

关键词: W/O型微乳, 迁移率, 富集

Abstract: The water-in-oil(W/O) microemulsions, which have been prepared by using the surfactant diethylhexyl sodium sulphasuccinate(AOT) and the oil solvent n-heptane, were used to transport and enrich trace metal ions Cd2+and Cr3+. The experimental results show that the two metal ions have high transport ratios(>90%) under the optimum conditions, Cd2+has high enrich times(6-7 times) and recovery ratio(100%), but Cr3+has very low enrich times(1-2 times) and recovery ratio(0%) under the given conditions of de emulsion.

Key words: W/O microemulsion, Transport, Enrich
