【摘要】：采用红外光谱分析技术研究了杂化沉淀聚合法制备的8-羟基喹啉锗印迹聚合物(MIPs)合成、吸附及解吸过程各阶段红外光谱变化,明确合成过程中各物料反应行为及吸附解吸对聚合物性质的影响。结果表明,三氯甲烷与甲醇的混合溶剂及引发剂偶氮二异丁腈不参与合成过程,功能单体丙烯酰胺、交联剂EGDMA参与聚合反应,在洗脱过程中模板8-羟基喹啉和锗离子被洗脱,而在吸附过程中又以固定结构被高效、高选择性吸附。
[Abstract]:The synthesis, adsorption and desorption of 8-hydroxyquinoline-germanium imprinted polymer (MIPs) by hybrid precipitation polymerization were studied by infrared spectroscopy. The reaction behavior of each material and the effect of adsorption and desorption on the properties of polymer were clarified. The results showed that the mixed solvent of trichloromethane and methanol and initiator azodiisobutyronitrile did not participate in the synthesis process, the functional monomer acrylamide and crosslinking agent EGDMA participated in the polymerization reaction, and the template 8-hydroxyquinoline and germanium ion were eluted during the elution process. In the process of adsorption, the adsorption was highly efficient and highly selective with fixed structure.
