采用γ-氨丙基三乙氧基硅烷对硅胶微球表面进行接枝修饰,然后以甲基丙烯酸为功能单体,二甲基丙烯酸乙二醇酯为交联剂,甲苯为溶剂,3-甲基噻吩为模板分子,在硅胶微球表面聚合,得到3-甲基噻吩的硅胶微球表面分子印迹聚合物,用红外光谱进行结构表征。通过考察模板分子、功能单体、交联剂、溶剂的用量等对吸附容量的影响,得到3-甲基噻吩、甲基丙烯酸、二甲基丙烯酸乙二醇酯、甲苯适宜的摩尔聚合比,以此配比合成了3-甲基噻吩表面印迹聚合物,在模拟汽油中,研究了该聚合物对3-甲基噻吩的吸附动力学、吸附选择性、竞争性及再生性能。结果表明,分子印迹聚合物对3-甲基噻吩具有良好的吸附选择性和再生性能,...

Based on grafting modification of silica microsphere surface with γ-aminopro-pyltriethoxysilane, surface molecularly imprinted polymers for 3-methyl thiophene were prepared with methacrylic acid as functional monomer, ethylene glycol dimethacrylate as cross-linker, toluene as solvent, and 3-methyl thiophene as template molecule. The final products were characterized with FT-IR. The effect of dosages of template molecule, functional monomer, cross-linker and solvent on adsorption capacity was investigated to determine the suitable molar ratio o...
