摘　　要：研究了以气溶胶ＯＴ（ＡＯＴ）为表面活性剂与不同烃类的油性溶剂及不同醇类的助表面活性剂一起制备的油包水（Ｗ／Ｏ）型微乳对Ｃｄ２＋从水相或料相迁移到微乳中的影响，同时还观察了油水比和温度对金属离子迁移的影响，从而确定了适于痕量金属离子迁移的微乳体系和以Ｃｄ２＋为示范离子的迁移条件。A kind of water-m-on (W/O) microemulsion was prepared with the Surfactant AOT in combination with different oil solvents and cosurfactants. It was employed to study the transport of metal ions, such as Cd2+.The effects of the volume ratio of oil to water, and the experimental temperature have been studied too.
