POLAROGRAPHIC AND VOLTAMMETRIC BEHAVIOR OF ENOXACIN

The polarographic and voltammetric behaviour of enoxacin is described. There was a well defined linear sweep voltammetric peak at about -1.0 52 V versus Ag/AgCl in 0.05 mol l(-1) H2SO4 solution. The peak current was proportional to the concentration of enoxacin in the range 1.0 X 10(-3)-1.0 x 10(-7) mol l(-1), and the LOD was 4 x 10(-9) mol l(-1). T he characteristics of the peak were examined in detail. The results pr oved that the reduction of enoxacin is irreversible and that the peak had adsorption characteristics. A mechanism is proposed for the reduct ion of enoxacin.
