In order to explore the optimum condition of transition of Pb, the transfer behavior of Pb through the emulsion liquid membrane system of TBP-Span80-atoleine-kerosene was studied. The study analyzed the effect of Pb transport rate of membrane phase component, pH values in external aqueous phase, acidness in internal aqueous phase, rew and concentration of metal ions in external aqueous phase. In the case of the optimal technological conditions, the waste water of Pb, Cu and Ni was treated.
