Abstract: In polyethylene glycol-inorganic salt-water system the liquid-liquid extraction behaviour of the complexes of copper (Ⅱ), Bismuth (M) and Zircon-ium(Ⅳ) with xylenol orange was investigated by using XOas extractant. The quantitative extraction separation of Cu(Ⅱ)-Zr(Ⅳ), Cu(Ⅱ)-Bi(Ⅲ) and Bi(Ⅲ)-Zr(Ⅳ) based on this system was carried out by controlling the acidity of the solution and adding some masking agents. The separation results are satisfactory. The extraction machanism for the system was also studied.
