中文摘要：

以镉离子为模板,甲基丙烯酸、4-乙烯基吡啶为功能单体,乙二醇二甲基丙烯酸酯为交联剂,制备了镉离子印迹聚合物。采用红外、扫描电镜、X射线衍射和热重分析技术对印迹聚合物进行了表征。通过静态吸附实验研究了印迹聚合物对模板分子的吸附容量及选择识别特性。结果表明,聚合物对镉离子的最大吸附容量为10.6 mg/g;Cd（Ⅱ）/Zn（Ⅱ）、Cd（Ⅱ）/Cu（Ⅱ）和Cd（Ⅱ）/Pb（Ⅱ）的相对选择性因子分别为15.7、9.0和12.5。考察了聚合物的动态吸附性能。结果表明,聚合对模板分子的富集倍数为150。该方法成功应用于实际水样中Cd（Ⅱ）检测,经加标实验测得Cd（Ⅱ）的回收率在96.0%~102.0%之间。

英文摘要：

Metal ion-imprinted polymer （liP） was prepared by using Cd（II） as the template, methacrylic acid and vinyl pyridine as monomers, and Ethylene Glycol Dimethacrylate as cross-linking agent. The ion-imprinted polymer were characterized by infrared spectroscopy （IR）, scanning electron microscopy （SEM）, X-Ray Diffraction （XRD） and thermogravimetry （TGA）. The batch experiments were performed to investigate the adsorption properties and selective recognition characteristics of the polymer for Cd（II）. The results showed that the maximum adsorption capacity of IIP for Cd（II） was 10.6 mg/g and the relative selectivity factor values of Cd（II）/Pb（II）, Cd（II）/Cu（II）, Cd（II）/Zn（II） were 12.5, 9.0 and 15.7, respectively. The column experiments suggested that the enrichment factor of IIP for Cd（II） was 150. The proposed method was successfully applied to determination of Cd（II） in water samples with satisfactory and the recoveries of water samples were about 96.0%-102.0%.
