Abstract: Molecularly imprinted polymers (MIPs) were prepared by precipitation polymerization using endosulfan as template，(MAA) and ethylene glycol dimethacrylate (EGDMA) as functional monomer and cross-linker respectively. Spectrophotometric analysis was used to study the interaction between template and functional monomer，and the adsorption efficiency was investigated by equilibrium adsorption experiments. The results showed that the imprinted polymer had higher adsorption efficiency compared to the blank polymer，which had the same chemical composition. Scatchard plot’s analysis revealed that the apparent maximum number of binding sites of the best imprinted polymer was 42.56 mmol/g.

摘要： 采用分子印迹技术，以α-甲基丙烯酸为功能单体，乙二醇二甲基丙烯酸酯为交联剂，偶氮二异丁腈为引发剂，乙腈为致孔剂，合成以硫丹为模板的印迹聚合物微球。首先利用紫外光谱方法研究了模板与功能单体相互作用情况，采用平衡吸附试验对印迹聚合物吸附效率进行了表征，与化学组成相同的空白聚合物相比，印迹聚合物微球对模板分子具有更高的吸附效率，按最佳合成条件得到的印迹聚合物最大表观吸附量达42.56 mmol/g。
