摘要
以L-色氨酸作为模板分子,丙烯酰胺为功能单体,N,N′-亚甲基双丙烯酰胺为交联剂,通过在聚甲基丙烯酸甲酯多孔基质球表面复合印迹层,制备了L-色氨酸表面印迹聚合物微球(SMIPs),探索了不同比表面积基质球及添加丙烯腈对SMIPs吸附性能的影响,结果表明基质球比表面积为432.0m2/g时,SMIPs对L-色氨酸的吸附量较高;当n(AN)∶n(L-trp)=3∶1时,SMIPs的综合吸附性能较好。
Molecularly imprinted polymers are prepared on the surface of porous polymethyl methacrylate precursor microspheres using L-tryptophan as template,acrylamide as functional monomer and N,N′-methylene-bis-acrylamide as cross-linker.The effects of the specific surface area of precursor microspheres and the addition of acrylonitrile on the adsorption of surface molecularly imprinted polymers (SMIPs) are discussed.The results show that the SMIPs exhibite higher adsorption capacity when the specific surface area of the precursor microspheres is 432.0 m2/g.The SMIPs possess better properties of adsorption when the molar ratio of acrylonitrile to L-tryptophan is 3∶1.
