摘要 应用三维荧光技术结合两种具有数学分离功能部分代替物理分离的二阶校正方法对牛奶中的弗洛沙星、培氟沙星及伊诺沙星进行了定量分析研究.该法不需要分离3种喹诺酮类药物,可以在牛奶干扰存在下实现对感兴趣分析物的同时快速定量测定,操作过程简单,灵敏度和选择性高,预测结果满意.AATLD(交替不对称三线性分解算法)解析得到的弗洛沙星的平均回收率为(97.87±4.91)%,培氟沙星的平均回收率为(97.55±5.45)%,伊诺沙星的平均回收率是(102.13±5.75)%. Three dimensional fluorescence spectrum combined with two kinds of second-order calibration algorithms with physical separation partially substituted by mathematical separation was developed for simultaneous quantitative determination of Fleroxacin ( FLE), Pefloxacin (PEF) and Enoxacin (ENO) in milk. The proposed method can perform simultaneous quantitative determination of interesting analytes in the presence of milk interference without separating the three kinds of quinolones, and the operation process is simple and has high sensitivity and selectivity and satisfactory prediction results. AATLD ( Alternating asymmetric trilinear de- composition) analysis result showed that the average recoveries of Fleroxacin (FLE) , Pefloxacin (PEF) and enoxaein (ENO) are (97.87 ±4.91)% , (97.55 ±5.45)% and (102.13 ±5.759)% respectively.
