| 摘 要： | 以恩诺沙星为模板分子,α-甲基丙烯酸为功能单体,二甲基丙烯酸乙二醇酯为交联剂,制备了恩诺沙星分子印迹聚合物。以该分子印迹聚合物为固相萃取材料,采用高效毛细管电泳分离方式,建立了分子印迹固相萃取-高效毛细管电泳检测鸡肉中恩诺沙星的方法。结果表明,该方法能有效地萃取和检测鸡肉中的恩诺沙星。在优化条件下,恩诺沙星的检出限为92.02 μg/kg,定量限为336.04 μg/kg;不同恩诺沙星添加水平下的回收率为77.84%～86.52%,相对标准偏差为2.18%～3.76%。该方法适用于鸡肉中恩诺沙星残留的测定。

| Abstract: | Molecular imprinted polymer targeted for enrofloxacin (ENR) was synthesized using ENR as the template molecules, α-methacrylic acid as the functional monomer and ethylene glycol dimethacrylate as the cross-linking agent. With the ENR molecular imprinted polymer, a molecular imprinted solid phase extraction-high performance capillary electrophoresis (MISPE-HPCE) method for the determination of ENR in chicken muscle was developed. The results showed that this method exhibited high selectivity and sensitivity for the determination of ENR in chicken muscle. Under the optimized conditions, the limit of detection and limit of quantification were 92.02 μg/kg and 336.04 μg/kg, respectively. The recoveries of the ENR spiked in chicken muscle at different levels were in the range of 77.84%~86.52%, and the relative standard deviations (RSDs) were in the range of 2.18%~3.76%. This MISPE-HPCE method is feasible for the analysis of ENR residue in chicken muscle. |
