| 摘 要： | 采用分子印迹本体聚合法,制备了对内分泌干扰物雌酮具有高选择识别能力的分子印迹聚合物。吸附动力学和选择性实验结果表明,与非印迹聚合物相比,印迹聚合物具有较高的吸附容量和吸附速率,对模板分子具有较高的选择性。聚合反应条件对印迹聚合物的吸附和识别性能有重要影响,以丙烯酰胺为功能单体,模板分子、功能单体和交联剂摩尔比为1:3:6,制备的印迹聚合物具有较高的选择和吸附性能。

| Abstract: | In this thesis, a highly selective imprinted polymer was synthesized by the bulk polymerization method, using estrone as template and acrylamide as functional monomers. 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, offered a faster kinetics for the adsorption of estrone than the non-imprinted sorbent. Results also indicated that polymerizing conditions had important effect on the selectivity of the imprinted polymer, and the 1:3:6 ratio of template to functional monomer and cross-linker was suitable for preparation an imprinted polymer having high adsorption capacity and selective ability. |
