以正丁醇为模板分子,采用本体聚合法制备了正丁醇分子印迹聚合物。利用扫描电镜和红外光谱对该聚合物进行表征,并利用动态吸附、静态吸附和选择性吸附实验评价其吸附性能。正丁醇分子印迹聚合物能够特异性识别正丁醇,通过计算得到正丁醇MIPs的分离因子α为2.057,印迹因子IF为2.123。此聚合物制备简单、可重复利用并且表现出良好的选择性,可作为固相萃取填料应用于食品中正丁醇的分离、富集和检测。
Using n-butanol as a template molecule, n-butanol molecularly imprinted polymer was prepared by bulk polymerization. The polymer was characterized by scanning electron microscopy and infrared spectroscopy, and its adsorption performance was evaluated by dynamic adsorption, static adsorption and selective adsorption experiments. N-butanol molecularly imprinted polymer can specifically recognize n-butanol. The calculated separation factor α of n-butanol MIPs is 2.057, and the imprinting factor IF is 2.123. The polymer is simple to prepare, reusable and shows good selectivity. It can be used as a solid phase extraction filler in the separation, enrichment and detection of n-butanol in food.
