The extraction of Pd(Ⅱ) by emulsion liquid membrane(ELM) method was investigated. In this liquid membrane system, N 503 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.
