摘　　要：以邻苯二甲酸二甲氧乙酯(DMOP)为模板分子,丙烯酰胺为功能单体,三羟甲基丙烷三甲基丙烯酸酯为交联剂,合成了邻苯二甲酸二甲氧乙酯印迹聚合物(DMOP-MIP)吸附材料。采用紫外光谱以及红外光谱对印迹聚合物制备进行表征,通过平衡吸附实验对DMOP-MIP的吸附性能进行评价。结果表明,DMOP-MIP对DMOP的最大吸附容量为18.2μmol/g,吸附在4h左右可达到平衡。DMOP-MIP对DMOP的吸附量高于其结构类似物邻苯二甲酸二甲酯和邻苯二甲酸二丁酯,表现出较高的选择性识别能力。Molecularly imprinted polymer for di（methoxyethyl）phthalate（DMOP-MIP）was synthesized with DMOP as template molecule,acrylamide as functional monomer and trimethylolpropane trimethacrylate as a crosslinking agent.The DMOP-MIP was characterized by fourier transform infrared spectroscopy（FTIR）and ultraviolet（UV）.And its adsorption property was evaluated by batch adsorption experiments.The obtained results revealed a maximum adsorbing capacity and a adsorption equilibrium time of DMOP-MIP towarded DMOP was about 18.2μmol /g and 4 h,respectively.In addition,the adsorbing capacity of DMOP-MIP for DMOP was higher than that for its structural analogues,dimethyl phthalate and dibutyl phthalate,indicating it had good selective recognition.
