摘　　要：研究了以聚氧乙烯失水山梨醇单油酸酯(吐温80)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微乳状液对钴离子从水相或料相迁移到微乳相中的影响,同时还观察了油水比和温度对钴离子迁移率的影响,最终得出了以吐温80为表面活性剂,正辛烷为油性溶剂,正庚醇为助表面活性剂的适用于痕量钴离子迁移的微乳体系及最佳迁移条件,结果令人满意。Microemulsions of water-in-oil （w/o） were prepared by mixing the surfactant Tween-80 with different hydrophobic solvents and other cosurfactants. The transporting behaviors of metal＇ions such as Co （Ⅱ） from the water or feed phases into the microemulsion phases in PAR systems were studied using spectrophotometric techniques. By comparing with the blank reagents, optimum conditions for preparing microemulsions and metal ion transport were obtained. The experimental results showed that the metal ions had high transport ratios in these microemulsion systems made of Tween-80 as the surfactant, 1-heptane as the hydrophobic solvent and 1-butanol as the cosurfactant. Satisfactory determinations of the target ions were carried out.
