| 摘 要： | 基于在酸性介质下磺胺嘧啶与碱性Luminol能产生化学发光,建立了化学发光微流动注射芯片测定鸡肉中磺胺嘧啶的方法。该芯片上微通道由激光雕刻机在聚甲基丙烯酸甲酯上雕刻而成,采用精确时间控制进样的方式检测,测定磺胺嘧啶线性范围为(4.0~50.0)×10-8g/ml,检出限1×10-8g/ml,对2.0×10-7g/ml磺胺嘧啶连续11次测定的相对标准偏差RSD为1.4%。

| Abstract: | A micro-flow injection chemiluminescence system for determination of sulfadiazine was described,based on luminol-sulfadiazine system.The flow channels were fabricated using laser on PMMA.The sampling time was controlled precisely by a timer.Under the selecting experimental conditions,the chemiluminescence intensity was linear with sulfadiazine concentrations of(4.0-50.0)×10-8 g/ml,the detection limit was 1.0×10-8 g/ml,and the relative standard deviation of 11 times of determination on 2.0×10-7 g/ml sulfadiazine was 1.4%. |
