Abstract
A study of the electrochemical behavior of piroxicam has been carried out by dc polarography, classical and differential pulse mode voltamme tric techniques, as well as by classical and differential pulse mode a dsorptive cathodic stripping voltammetry (AdCSV), in methanol/H2O(20/8 0% v/v) and acetonitrile/H2O(20/80% v/v) media. Several parameters, su ch as pH, temperature, scan rate, ad-accumulation potential, and accum ulation time, elucidate the piroxicam reduction mechanism and establis h analytical methods, mainly by AdCSV, obtaining a detection limit of 2.4 x 10(-11) M.
