摘要

采用分子印迹沉淀聚合法,以丙烯酰胺的结构类似物丙酰胺为模板分子,制备出了对丙烯酰胺具有较好选择性的印迹聚合物。通过振荡吸附实验对聚合物的合成条件进行了优化;吸附动力学和选择性实验结果表明:与本体聚合法相比,印迹聚合物具有较高的吸附容量和吸附速率,对目标分析物丙烯酰胺具有较好的吸附特性,最大吸附量为6.67 mg/g。

Abstract

An acrylamide molecularly imprinted polymer was synthesized by precipitation polymerization using propionamide as a template.The conditions of preparation were optimized.The imprinted polymer was evaluated by the kinetic and selective adsorption experiments.The results showed that the imprinted functional sorbent exhibited good recognition and selective ability,a faster kinetics for the adsorption of acrylamide than that made by the bulk polymerization method.The max adsorptive capacity was 6.67 mg/g.
