Abstract: Using nickel (II) acetate-2, 2'-dipyridyl complex as template, 4-vinylpyridine as the functional monomer and ethylene glycol dimethacrylate(EDMA) as the cross linker, a new kind of metal-complexing template molecular imprinting polymer (MIP) was prepared. The effects of metal ions on the binding capacity of MIP was studied. The results of equilibrium binding experiments show that the MIP has high selectivity to nickel (II)-2, 2'-dipyridyl complex. The binding characteristics of MIP were evaluated with Scatchard plot, the equilibrium dissociation constant Kd1 and the apparent maximum number Qmax1 of the higher affinity binding sites could be calculated to be 0.082 mmol/L and 82.2 μmol/g. For lower affinity binding sites, Kd2 = 0.400 mmol/L, Qmax2 = 91.3 μmol/g
