　　在硅胶表面以邻苯二甲酸二甲酯（DMP）为模板分子，甲基丙烯酰胺（MAM）为功能单体，N，N-亚甲基双丙烯酰胺（ MBAA）为交联剂在甲醇/水体系中制备了DMP印迹聚合物。采用紫外光谱法（ UV）研究单体与模板间的相互作用，红外光谱分析印迹聚合物的结构特征。用平衡吸附实验方法研究聚合物对 DMP的结合性能，Scatchard法分析聚合物的吸附解离常数（Kd）和最大表观吸附容量（Qmax）。对不同底物的选择性实验表明聚合物对模板分子具有良好的亲和性和选择性。将MIP用作固相萃取（ SPE ）柱填料，对环境水样中的DMP进行富集试验，回收率为90.28-95.25％，相对标准偏差（ RSD）为3.52-7.61％。

Molecularly imprinted polymers ( MIP) for dimethyl phthalate ( DMP) was synthesized on the surface of silica gel with DMP as template molecule , methylacrylamide ( MAM ) as functional monomer and N, N′-methylenebis acrylamide ( ( MBAA ) ) as a crosslinking agent in methanol-water system.The intermolecular interaction between MAM and DMP was confirmed by ultraviolet spectroscopy(UV)and the structure of MIP was analyzed by fourier transform infrared spectroscopy (FTIR).The binding properties of the MIP were evaluated by equilibrium adsorption experiment method.The dissociation constant ( Kd ) and the max adsorption ca-pacity(Qmax)of the template-polymer system was analyzed via scatchard plot.The experiments of binding different substrates indica-ted that the MIP possessed good affinity and selectivity for DMP.In addition,the MIP was successfully used as a stationary phase for solid-phase extraction ( SPE) to enrich DMP from several environmental water samples and the recoveries were in the range of 90.28-95.25%with RSD of 3.52-7.61%.
