摘　　要：研究了依诺沙星在胶束体系中的荧光特性,发现十二烷基硫酸钠(SDS)胶束对依诺沙星的荧光有显著的增敏作用,据此建立了直接测定人体尿样中依诺沙星的荧光分光光度法.用于样品分析,当依诺沙星浓度在2.0×10-7-4.0×10-6mol/L范围内,荧光强度与浓度呈良好的线型关系,检出限为1.4×10-8mol/L,回收率为96-103％.The fluorescence of Enoxacin in micellar system is studied. The experiments show that sodium dodecyl sulfate (SDS) micellar system can greatly enhance the fluorescence of Enoxacin. A new method using the fluorophotometric analysis is developed for the determination of Enoxacin in human urine. Linear relationship is kept between the fluorescence intensities and the Enoxacin concentrations within the range of 2.0×10-7-4.0×10-6 mol/L. The detection limit is 1.4×10-8mol/L and the recovery is within the range of 96-103%.
