【摘要】 采用溶胶凝胶表面分子印迹技术，以纳米级二氧化硅为载体，以布洛芬为模板分子，3-氨丙基三乙氧基硅烷（APTES）为功能单体，正硅酸乙酯（TEOS）为交联剂，合成了布洛芬分子印迹聚合物（MIPs）。使用扫描电镜（SEM）对合成的MIPs进行了形貌表征，通过静态吸附实验、动态吸附实验、选择性实验以及再生利用实验评价了MIPs对布洛芬的吸附性能。结果表明，MIPs对布洛芬可在150 min时达到吸附平衡，饱和吸附容量可达45.9 mg/g，印迹因子为1.7，与非分子印迹聚合物相比，MIPs对布洛芬具有特异性识别性能。此外，MIPs经过5次循环使用后，对布洛芬的吸附容量仍保持在初始的87.6%以上，有较好的重复利用性能，能够作为一种良好的对布洛芬具有高选择性和高吸附容量的新型吸附功能材料。更多还原

【Abstract】 Using ibuprofen as template molecule, 3-aminopropyl triethoxysilane(APTES) as functional monomer and ethyl orthosilicate(TEOS) as crosslinking agent, molecularly imprinted polymers(MIPs) were synthesized by solgel method and surface imprinting technology. The morphology of the synthesized MIPs was characterized by scanning electron microscopy(SEM). The adsorption behavior of ibuprofen on MIPs was evaluated by static and dynamic adsorption experiments, and the high selectivity of MIPs to ibuprofen was evaluated by selective experiment. The results showed that MIPs could achieve adsorption equilibrium with ibuprofen at 150 min, and the imprinted factor was 1.7, and the saturated adsorption capacity was 45.9 mg/g. Compared with non-imprinted polymers, MIPs had specific recognition and high selectivity for ibuprofen. In addition, the adsorption capacity of ibuprofen molecularly imprinted polymer prepared by sol-gel method was more than 87.6% after 5 cycles, indicative of good reusability. Therefore, the synthesized molecularly imprinted polymers have a good application prospect for the recognition and adsorption of ibuprofen.更多还原
