With Cu(Ⅱ) ions as the template, molecular imprinted polymer membranes with supporting membranes were synthesized by UV irradiation. The surface features of the membranes were analyzed by scanning electron microscopy. The imprinted membranes exhibited selective permeation for Cu(Ⅱ) ions (compared to Zn(Ⅱ) ions, Ca(Ⅱ) ions etc). Effects of different supporting membranes, porosifier and functional monomers on the imprinted membranes' structure and permeation characteristics were investigated respectively, and pH value, cation and anion effects were also investigated. The results indicated that the membranes synthesized with PVDF membrane and cupric acetate exhibited selective permeation for Cu(Ⅱ) ions when the pH was 1 and the anion was acetate.
