摘要:
为了提高工业上分离提纯天然维生素E的效率，以聚苯乙烯微球为种球，维生素E（VE）为模板分子，甲基丙烯酸为功能单体，二甲基丙烯酸乙二醇酯为交联剂，采用二步溶胀聚合法制备了VE分子印迹聚合物，利用红外光谱仪，扫描电子显微镜表征印迹聚合物的组成和微结构并采用静态吸附实验分析印迹聚合物对VE的结合能力，结果表明，印迹聚合物具有良好的球形度和吸附效果，对VE的吸附量达到了38.12 mg/g。采用Langmuir模型与Freundlich模型对等温吸附曲线进行拟合，发现Freundlich模型能更好的拟合实验数据；Scatchard分析表明印迹聚合物中存在两类不同的结合位点。此方法合成的印迹聚合物微球对VE有较好的结合性能，可应用于VE的工业分离提纯。
Abstract:
To purify the Vitamin （VE）， we synthesized a molecularly imprinted polymer （MIP） via a two-step swelling method， in the presence of polystyrene microspheres as the substrate， methacrylic acid as the functional monomer and ethylene glycol dimethacrylate as the cross-linker. The composition and microstructures of the MIPs were characterized by infrared spectroscopy and scanning electron microscopy. Their performances in VE purification were investigated by adsorption experiments. It is found that the MIP possesses good sphericity and a high adsorption capacity （38.12 mg/g） in chloroform solution. The MIP presents a higher capacity than the non-imprinted polymer （NIP） towards VE. The Freundlich model is a better equation to describe the VE adsorption onto the MIP than the Langmuir model. The synthesized MIPs is suitable for the separation and purification of VE in industry.
