Abstract

Introduction: Dyes are visible materials and are considered as one of the hazardous components that make up industrial waste. Therefore it is removed from bodies of water, using various methods. In this regard, the Fenton oxidation process is one of the most effective ways to remove colored contaminants in aquatic environments, which has many applications today. Materials and Methods: In this empirical study, the effect of the Fenton oxidation process in the removal of the soluble synthetic dye, Reactive Red 2 (RR2), has been studied. The color removal efficiency of the Fenton process in the presence of ferrous sulfate and hydrogen peroxide at different reaction variables were studied in the Jar Test when initial concentration of the dye was 10 mg/L at constant pH = 3 and lab temperature. Results: The results showed that concentrations of hydrogen peroxide and iron ions influence the maximum removal efficiency. Conclusion: According to the survey results, Fenton oxidation is an effective method for the removal of RR2 dye from aqueous solutions. © 2017. All Rights Reserved.
