In this study, degradation of Reactive Black 5 (RB5) as a reactive azo dye from aqueous solutions has been performed by an integrated system namely sono–photo-Fenton (H2O2/Fe/UV/US). The Fenton/ UV/US process could show synergistic removal of dye, as compared to Fenton/UV or Fenton process. Batch reactor based on one factorial optimization has been applied for operational parameters: reaction time, pH, H2O2 dosage, Fe2+ dosage, and initial RB5 concentration. The integrated system significantly removed dye (100%) at the best conditions pH of 3, 50 mg L–1 Fe2+, 200 mg L–1 H2O2, 100 mg L–1 RB5 concentration, and reaction time of 30 min. The present study demonstrated that the sono–photo-Fenton could be used as an efficient, reliable method for the removal of RB5 from water and wastewater.
