- Phenol is classified as priority pollutant. Phenol and its derivatives are stable in water, environmental contamination, and health concerns that are used as raw material in many chemical industries. This study investigated the removal of phenol by electro-H2O2/UV system.The response surface methodology (RSM) using central composite design (CCD) was used to modeling and optimization of experimental parameters such as pH, contact time, initial concentration of phenol, concentration of hydrogen peroxide, and current density.The obtained results demonstrated that the efficiency of the electro-H2O2/UV system was maximum (>99%) under the optimal conditions for the phenol removal from aqueous solutions, 2 mM of hydrogen peroxide concentration, 50 mg/L of initial phenol concentration, pH of 5, 10 mA/cm2 of current density, reaction time of 25 min and 2.1 kW h/m3 of energy consumption. Therefore, the electro-H2O2/UV system is an efficient method for the removal of organic compounds from industrial wastewater.
