摘要
采用以Ｎ，Ｎ－二（１－甲庚基）乙酰胺（以下称Ｎ５０３）为流动载体、兰１１３Ａ为表面活性剂、煤油为膜溶剂、ＨＣｌ溶液做内相试剂的乳状液膜从氯化物体系中提取汞（Ⅱ），研究其迁移反应机理。实验表明，在所筛选的适宜制乳、迁移提取等最佳条件下，９９％以上的汞（Ⅱ）迁入内相。
Mercury(Ⅱ)was extracted from chloride system by the emulsion liquid membrane. In this liquid membrane system, N503 is used as mobile carrier, Lan 113 A as surfactant, kerosene as solvent, and HCl solution as inner phase. The transport reaction mechanism was evidenced conclusively. The study indicated that under the optimum experimental conditions more than 99% Hg(Ⅱ)was transported into inner phase.
