【摘要】 研究了以二－（2－乙基已基）磺化琥珀酸钠为表面活性剂、以正庚烷为油性溶剂的W／O型微乳状液的形成及迁移痕量金属离子的行为，确定了制乳和迁移的适宜条件．在此条件下，一些金属离子可较完全地从水相或料相迁移到微乳相中，显示出较高的迁移率．更多还原

【Abstract】 The water-in-oil(W/0) microemulsions have been prepared by using the surfactant diethylhexyl sodium sulphasuccinate and the oil solvent n-heptane. The transporting behavior of metal ions, such as Cu2+, Zn2+, Pb2+, Cd2+, Hg2+, Co2+, Ni2+, Cr3+ and Cr(VI ),has been studied from the water phases or feed phases into the microemulsion phases. The optimum conditions of preparing microemulsions and transporting metal ions have been obtained. The experimental results show that all of these metal ions studied except Cr(VI )have high transport ratios under these conditions.更多还原
