Abstract: An optical approach was developed for the detection of Cd2+ based on ion imprinted polymer membrances as sensing receptors. The polymer was synthesized with cadmium ions as a template and 2-naphthyl acrylate as both the fluorescence tag and a complex-forming agent. The free radical polymerization was performed within PVDF films and was initiated by 2,2'-azobisisobutyronitrile at 65 C in dimethyl sulfoxide. The polymer showed a high selectivity for cadmium ions.The calibration curve was linear over the Cd2+ concentration range of 1-9 μmol/L with a detection limit of 5.510-7 mol/L. Compared with that by the ICP-MS method, the results by this method had no obvisous difference. The RSDs(n=10) of the polymer for Cd2+ was 2.3%,and the recoveries for Cd2+ in spiked river water were in the range of 97%-100%.
