摘要：

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