摘要

采用沉淀聚合法制备分子印迹聚合物(MIP)，用于饮用水中聚合物包装中DEHP和DBP的检测。用DEHP和DBP与甲基丙烯酸甲酯(MMA)和三甲基丙烷三甲基丙烯酸酯(TRIM)交联得到MIP。采用FTIR、SEM-EDS、UV-Vis和SAA对聚合物(MIP_DEHP, MIP_DBP)的性质进行了表征。所得材料具有介孔结构，颗粒小、均匀、多孔。MIP_DEHP的比表面积和总孔隙体积比MIP_DBP小2倍以上，孔径略大。较低的C含量可能预示着MIP_DEHP和MIP_DBP的形成。FTIR法证实了-CH， -CO， -C =C和-C =O的存在。MIP_DEHP和MIP_DBP的吸附量分别为0.68 mg/g和1.06 mg/g，符合Freundlich等温吸附模型。

Synthesis of molecularly printed methyl methacrylate-based polymers for the detection of di(2-ethylhexyl) phthalate and dibutyl phthalate

Molecularly imprinted polymers (MIP) were obtained by precipitation polymerization for the detection of DEHP and DBP from polymer packaging in drinking water. MIP was obtained by cross-linking DEHP and DBP with methyl methacrylate (MMA) and trimethylolpropane trimethacrylate (TRIM). FTIR, SEM-EDS, UV-Vis and SAA were used to determine properties of polymers (MIP_DEHP, MIP_DBP). The obtained materials were characterized by a mesoporous structure with small, uniform, and porous grains. The surface area and total pore volume of MIP_DEHP were more than twice smaller than MIP_DBP, with a slightly larger pore diameter. Lower C content may indicate the formation of MIP_DEHP and MIP_DBP. The FTIR method confirmed the presence of functional groups –CH, –CO, –C=C and –C=O. The adsorption capacity of MIP_DEHP and MIP_DBP was 0.68 mg/g and 1.06 mg/g, respectively, and was consistent with the Freundlich isothermal adsorption model.
