Polarographic and voltammetric behaviour of enoxacin

Abstract

The polarographic and voltammetric behaviour of enoxacin is described. There was a well defined linear sweep voltammetric peak at about –1.052 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 × 10^–3–1.0 × 10^–7 mol l^–1, and the LOD was 4 × 10^–9 mol l^–1. The characteristics of the peak were examined in detail. The results proved that the reduction of enoxacin is irreversible and that the peak had adsorption characteristics. A mechanism is proposed for the reduction of enoxacin.
