Electrochemical studies of some quinolone antibiotics. Part II. Determination by differential pulse polarography in substance and in pharmaceutical formulations.

Differential pulse polarography was used to study quinolone antibiotics: ciprofloxacin, enoxacin, norfloxacin, ofloxacin and pefloxacin on a mercury electrode. The optimal parameters and background solutions have been chosen. New polarographic method of quinolone determination in pure form and pharmaceutical formulations was found. Statistical analysis of the results obtained showed that proposed method is of good accuracy and precision.
