Spectrophotometric Determination Of Ornidazole And Norfloxacin In Tablets
Two simple spectrophotometric methods for the determination of ornidazole and norfloxacin in pharmaceutical preparations have been developed. First method is based on simultaneous equations. In the second method, derivative spectroscopy is used to eliminate spectral interference. Both drugs obey Beer's law in the concentration range employed for the analysis. The results of analysis have been validated statistically and by recovery studies.
