基于新功能单体的苯酚分子印迹聚合物的制备及其性能研究

 合成了一种新型功能单体1-苯基-3-甲基-4-甲基丙烯酰基-5-吡唑酮(PMMP).采用牺牲硅胶法,通过正交试验设计,从功能单体的用量、交联剂的用量和致孔溶剂的种类3个因素各取4个水平分别合成了16个苯酚分子印迹聚合物及相应的非印迹聚合物.平衡吸附实验表明正交设计优化条件下得到的印迹聚合物MIP17具有较大的吸附容量和较好的印迹效果.对MIP17进行了混合标准样品的选择性及实际样品的应用研究,结果表明应用该新功能单体制备的苯酚分子印迹聚合物具有较好的选择分离性能和一定应用潜能.

Preparation and properties of phenol molecular imprinted polymers with a new functional monomer

A series of phenol molecular imprinted polymers(MIP1—17)were prepared with a new functional monomer 1-phenyl-3-methyl-4-methacryloyl-5-pyrazolone(PMMP)by orthogonal design table of L16(45)considering 3 factors:the kind of porogen solvent,the dosage of functional monomer and that of cross linker.The optimum molecular imprinted polymer(MIP17)was furthermore used in a mixed standard sample to study its selectivity.And the separation of a real phenol-contained water system was also investigated with this MIP17 solid phase extraction column.The results showed that MIP17 prepared using PMMP as functional monomer showed better selectivity,indicating a certain potential application in separation and enrichment of phenol.
