| 摘 要： | 以酞酸二丁酯(DBP)作为模板分子,甲基丙烯酸作为功能单体,乙二醇二甲基丙烯酸酯(EDMA)作为交联剂,在硅胶表面合成分子印迹聚合物(MIPs)。通过红外、热重分析、比表面积测定等对聚合物进行分析和表征;采用静态吸附法对水相中的印迹聚合物的吸附性能进行考察.红外结果表明硅胶表面存在对模板分子具有识别功能的官能团;热重分析证明其良好的热稳定性;通过测定计算印迹膜厚度;静态吸附实验说明印迹聚合物具有良好的吸附性能.

| Abstract: | In this thesis, using DBP as a template molecule, MAA as functional monomer, EDMA as cross-linking agent, on the silica surface, the molecularly imprinted polymers （MIPs） were prepared. FTIR and thermogravimetric analysis （TGA） were employed to characterize the product. The property of adsorption was tested using static adsorption method in water. And then the imprinting and recognition mechanism was also studied. The results of FTIR indicate that there are recognition groups in the microspheres after imprinting. The thickness of imprinted membrane was determined. The result of static adsorption experiment shows that the adsorbent of MIPs has a high saturation adsorption capacity. |
