Mercury ion separation from another metal ions has been carried out in phase system consisted of propanol, NaCl and KI. The results showed that propanol could extract the associates formed by mercury with iodide. Hg(Ⅱ) can be separated completely from Fe(Ⅲ), Co(Ⅱ), Mn(Ⅱ), Mo(Ⅵ) and Zn(Ⅱ) in solution system of pH=2.0.
