研究了以 N，N-二(1-甲庚基)乙酰胺(N503)为流动载体、兰113A 为表面活性剂、煤油为膜溶剂，EDTA 做内相试剂的乳状液膜体系迁移钯的机理；其迁移钯的反应经紫外可见光谱证实为阴离子交换反应。在所筛选出的适宜制乳及迁移提取等最佳条件下，98% 以上的钯迁入内相。
The extraction of Pd(Ⅱ) by emulsion liquid membrane(ELM) method was investigated. In this liquid membrane system, N503 was used as mobile carrier,Lan 113A as surfactant,kerosene as solvent, and EDTA solution as inner phase. The transport reaction of Pd(Ⅱ) was proved to be an anion exchange reaction by UV and Visual spectra.More than 98% Pd(Ⅱ) is transported into inner phase under optimum experimental conditions.
