Abstract :In the present work, the electrochemical reduction of phenazopyridine hydrochloride insert ignore into journalissuearticles values(PAP); was carried out on glassy carbon insert ignore into journalissuearticles values(GCE); electrode in different supporting electrolyte/solvent systems by cyclic voltammetric insert ignore into journalissuearticles values(CV); technique. The best results for PAP were obtained in 0.1 M tetrabuty ammonium iodide /dimetyl sulfoxide insert ignore into journalissuearticles values(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.
