摘要
采用分子印迹技术合成了对有机磷农药久效磷有高度选择性的聚合物,通过1H NMR和紫外光谱研究了印迹聚合物的结合机理和识别特性。结果表明,该聚合物通过协同氢键作用形成1∶2型氢键配合物专一地结合久效磷。聚合物红外光谱研究表明,聚合物表面存在可与印迹分子相互作用的官能团。
In the present study, molecular imprinting was used to develop a method based on noncovalent interaction for the synthesis of a monocrotophos-specific polymer. The selective binding characteristics of the template polymer were evaluated by ^1H NMR and ultraviolet spectrometry. The polymer obtained was found to interact specifically with monocrotophos by cooperative hydrogen bonding. The infrared spectrometry of the polymer further indicated that there were some functional groups in the moleculary imprinted polymer which could interact on the template.
