以杨梅黄素(MYR)为模板分子、2-乙烯基吡啶(2-VP)为功能单体、二甲基乙二醇丙烯酸酯(EDMA)为交联剂,偶氮二异丁腈(AIBN)为引发剂,甲醇为致孔剂,采用分子印迹技术制备了杨梅黄素分子印迹聚合物(MYR-MIP)。通过红外光谱、扫描电镜、热重分析等技术表征了MYR-MIP的理化性能;采用紫外光谱分析研究了MYR-MIP对MYR的等温吸附和动力学吸附特性,研究结果表明MYR-MIP对MYR具有良好的特异性吸附,并且在2 h内达到平衡吸附;高效液相色谱分析表明MYR-MIP对MYR具有优良的选择识别特性。
Using MYR as template, 2-vinylpyridine (2-VP) as functional monomer, dimethyl ethylene glycol acrylate (EDMA) as crosslinking agent, azobisisobutyronitrile (AIBN ) As initiator and methanol as porogen. Myricetin molecularly imprinted polymer (MYR-MIP) was prepared by molecular imprinting technique. The physicochemical properties of MYR-MIP were characterized by infrared spectroscopy, scanning electron microscopy and thermogravimetric analysis. The isothermal adsorption and kinetic adsorption characteristics of MYR-MIP by MYR-MIP were studied by UV spectroscopy. The results show that MYR-MIP has Good specific adsorption, and reached equilibrium adsorption within 2 h; high performance liquid chromatography analysis showed that MYR-MIP MYR has excellent selection and identification characteristics.
