Fluorescence Characteristics of Norfloxacin Nicotinate and Norfloxacin Lactate and Its Application

The fluorescence characteristics of norfloxacin nicotinate and norfloxacin lactate in the different mediums were studied.The contents of norfloxacin nicotinate and norfloxacin lactate were determined by spectrofluorometry.The relationships of fluorescence intensity and concentration were good linear in 0.025—2.5μg/mL for norfloxacin nicotinate and in 0.01—2μg/mL for norfloxacin lactate,respectively.
