In this work, efficiency of UV/H₂O₂ process in the removal of Phenazopyridine (PhP) as a model contaminant from pharmaceutical compounds was investigated. For this purpose, a suitable batch re-circulated annular photoreactor with a replaceable UV-C lamp in the center of photoreactor was used. Effect of operational parameters such as initial PhP concentration, H₂O₂ concentration, UV-light source power and pH of the solution was investigated. Results indicate UV/H₂O₂ process is a powerful method for removal of PhP from aqueous solutions so that a considerable removal of this contaminant has been obtained in the short irradiation time.
