Studies on the Degradation of Cefotaxime and Voltammetric Behaviour of Degradation Product

Abstract

Abstract: The degradation of cefotaxime was carried out in NaOHsolution at 100℃ for 20min.Asensitive reduction peak of degradation product was obtained by adsorptive stripping voltammetry in 0.1 mol/L NaOH, at accumulation time of 60 s.E_p=-0.78 V (vs.Ag/AgCl).i_p is directly proportional to the concentration of cefotaxime over the range from 1.0×10^-9 to 1.0×10^-6 mol/L, with a detection limit of 5.0×10^-10 mol/L.The voltammetric behaviour of degradation product has been studied.The parameters of electrode reaction have been determined.The mechanisms about the degradation and electrode reactions were discussed.

Key words: Cefotaxime, Degradation, Adsorptive stripping voltammetry
