Investigation of Hybrid Process of Fenton Oxidation and Adsorption in Phenol Removal from Water

Abstract

Phenol is one of the aromatic hydrocarbons with high toxicity and adverse health effects on living beings. It can be found in wastewater from industries such as chemical and petrochemical industries and oil refineries. The aim of this study is to evaluate the c hybrid process of Fenton oxidation and adsorption on removal of phenol from water. In this paper an experimental study in laboratory scale is implemented. Variables such as: concentration of Fe2+, H2O2, pH, activated carbon and time are tested in order to impact on the rate of removal of phenol in water. Finally, optimal conditions for the removal of phenol through the hybrid process of adsorption test and oxidation Fenton test is introduced. Results show that 95, 94 and 96 percent of Phenol is removed, respectively with initial concentration of 50,150 and 250 mg/L by combination of adsorption test and Fenton test, in pH = 3, Fe2+ = 10 mg/L, H2O2 = 150 mg/L, activated carbon = 2.5 g/L and time = 90 min. It can be concluded that hybrid process of adsorption and oxidation of Fenton can be used as a suitable method to reduce of Phenol from water.
