【Abstract】 The fluorescence characteristics of enoxacin in micellar systems were studied in details. It was found that sodium dodecyl sulfate could greatly enhance the fluorescence signal of enoxacin in pH 7.5 Britton-robinson buffer solution. A new sensitive method using the synchronous fluorimetry was developed for the direct determination of enoxacin in human plasma. The linear range is 0.10～3.5 mg/L, with a detection limit of 0.10 mg/L and the recovery of the method is within the range of 96.9%～99.5% with a relative standard deviation below 2.3%.更多还原
