Abstract This study investigated Advanced oxidation process (AOP) utilizing photo-Fenton system (UV/H2O2/Fe+2) in treatment of wastewater contaminated with dyes. The experiments were carried out by batch systems. Acid Blue-9 dye (AB-9) was used as a model for dyes in wastewater. The experiments were conducted using Pyrex glass cylinder two liter volume reactor. The influence of different variables in batch experiments: H2O2 (10-800mg/L), Fe+2(5-100mg/L), pH (2–5) and initial concentration of AC-9 (25–150 mg/L) and their relationship with the oxidation efficiency were studied. In batch photo-Fenton system, the experimental results showed that the reagents required for complete removal (AC-9) (50mg/l) were: H2O2=800mg/L, Fe+2 =50mg/L under acidic condition (pH=2), temperature =20°C and irradiation time of 150 min. The result shows that the oxidation reagent H2O2 plays a very important role in dyes removal, and they final removal efficiency reached 99%.
