| 中文摘要:采用原子转移自由基聚合与片段印迹技术相结合的方法，以磺胺类物质的结构类似物4，6-二氯嘧啶为模板合成印迹聚合物。以4，6-二氯嘧啶(模板)︰甲基丙烯酸缩水甘油酯(功能单体)︰2，2′-联吡啶(配体)的摩尔比为10︰180︰1合成印迹聚合物。控制反应温度为60 ℃，反应时间为5 h。印迹聚合物的吸附量为1.48 mg/g，非印迹聚合物的吸附量为0.73 mg/g。以合成的聚合物为新型材料，对样品中的兽药残留进行选择性分离、富集，结果表明印迹聚合物的选择吸附能力明显优于非印迹聚合物。通过电镜扫描对聚合物的表面形态进行了表征。 |

| Abstract:Molecularly imprinted polymers were synthesized by atom transfer radical polymerization with fragment imprinting technique with the structural analogue of sulfonamide,4,6-dichloropyrimidine as template.The imprinted polymers were synthesized using 4,6-dichloropyrimidine (template),glycidyl methacrylate(functional monomer) and 2,2′- bipyridine(ligand) by the molar ratio of 10∶180∶1 at a reaction temperature of 60 ℃ and a reaction time of 5 h.The adsorption capacity for the synthetic imprinted polymers was 1.48 mg/g while that for non-imprinted polymers was 0.73 mg/g. The synthetic polymers were used as a new material for the selective separation and enrichment of veterinary drug residues in samples.The results showed that the selective adsorption capacity for the imprinted polymers was better than that for the non-imprinted polymers.The surface morphology of the polymers was characterized by scanning electron microscopy. |
