摘 要:筆者利用化學(xué)計量學(xué)交替懲罰三線(xiàn)性分解二階校正算法結合熒光分析,在有干擾藥物及牛奶中干擾組分共存下,對牛奶中的洛美沙星進(jìn)行快速分析測定。當三維熒光數據的預估組分數取4時(shí),所得平均回收率達到99.4%±1.3%,預測方差均方根(RMSP)為2.97 nmol/L,預測結果良好。實(shí)驗結果表明,此法可用于干擾組分共存下牛奶中洛美沙星的快速定量測定。

Abstract:A simple method for direct determination of lomfloxacin in milk even in the presence of other uncalibrated interferents was described in this paper. This second-order calibration was based on the alternating penalty trilinear decomposition algorithm coupled with fluorescence spectroscopy. When the estimated component number in three-way fluorescent responses was set to 4,the obtained recovery of lomefloxacin in milk was 99.4%±1.3%,and the root-mean-square error of prediction(RMSP) was 2.97 nmol/L. The satisfactory result indicated that the proposed method could be applied to simply quantify lomefloxacin in milk even in the presence of unknown interferences.
