  • 摘要: 本文以γ-甲基丙烯酰氧基丙基三甲氧基硅烷（KH570）修饰的TiO2纳米线为载体，邻苯二甲酸二甲酯（DMP）为模板分子，甲基丙烯酸（MAA）为功能单体，三羟甲基丙烷三甲基丙烯酸酯（TRIM）为交联剂，偶氮二异丁腈（AIBN）为引发剂，乙腈-甲苯（3∶1，V/V）为溶剂，采用沉淀聚合的方式制备DMP表面分子印迹材料.紫外光谱法、核磁共振和分子模拟表明MAA与DMP通过氢键以2∶1结合.采用红外光谱仪、透射电子显微镜、热重分析仪、粒度分析仪表征了材料的特性，采用聚合物吸附热力学、吸附动力学和吸附特异性表征了材料的吸附性能.该材料制备成固相萃取柱后能应用于环境土壤中DMP的测定.
    Abstract: In this paper, a novel surface molecularly imprinted polymer(MIP) was prepared using γ-methacryloyloxypropyltrimethoxysilane(KH570) modified TiO2 nanowire as supporter, dimethyl phthalate(DMP) as template, methacrylic acid(MAA) as functional monomer, trimethylolpropane trimethacrylate(TRIM) as crosslinker,azodiisobutyronitrile(AIBN) as initiator, and acetonitrile-toluene(3:1, V/V) as porogen. Ultraviolet spectrometry(UV), nuclear magnetic resonance(NMR) and molecular simulation revealed that MAA binds to DMP through hydrogen bonds with a ratio of 2:1. The properties of MIP were characterized by infrared spectrometry(IR), transmission electron microscope(TEM), particle size analyzer and thermogravimetric analyzer(TG). The MIP was packed into SPE cartridge and applied in the determination of DMP residues in soil.
