摘要：
A novel high selective and sensitive fluorescence probe termed gatifloxacin was discovered based on fluorescence "on -off' phenomenon in the presence of Se(IV). In the Tris-HCl/acetonitrile(3:7, volume ratio, Tris-HCl 0.05 mol/L, pH=7.3) system, the fluorescence intensity of gatifloxacin was linearly decreased with the concentration increase of Se(IV) in a range of 1.0x10(-5)-5.0 x 10(-5) mol/L with a correlation coefficient of 0.9979(R-2=0.9958) and in a range of 5.0 X 10(-5)-1.0 X 10(-4) mol/L with a correlation coefficient of 0.9973(R-2=0.9946). The detection limit of Se(IV) was 1.70x 10(-6) mol/L.
