Abstract


In the present work, the electrochemical reduction of phenazopyridine hydrochloride (PAP) was carried out on glassy carbon (GCE) electrode in different supporting electrolyte/solvent systems by cyclic voltammetric (CV) technique. The best results for PAP were obtained in 0.1 M tetrabutyammonium iodide/dimetyl sulfoxide (TBAI/DMSO) non-aqueous system by CV technique.  In this media,  three irreversible cathodic peaks were observed about -0.7 V, -1.7 V and - 2.0 V for PAP. With the scan rate measurements the process was found diffusion controlled. The possible reduction mechanism of PAP was also discussed.
