Title

Treatment of Aqueous Solution Containing Acid red 14 using an Electro Peroxone Process and a Box-Behnken Experimental Design

Pages

  48-57

Abstract

 Background & Aims of the Study: Azo dyes utilized in industrial processes, such as the textile manufacturing, lead to the creation of huge amounts of colored wastewaters that contain non-organic and organic constituents. Therefore, it is necessary to search for remedies in this regard. This study investigated the degradation and mineralization of Acid red 14 (AR14), which is a mono Azo dye generally employed in textile manufacturing, using an Electro peroxone process. The Electro-peroxone is a grouping of ozone and electrochemically generated hydrogen peroxide that can result in the production of strong hydroxyl radicals. Materials and Methods: This project was accompanied on synthetic wastewater that holds a high concentration of Acid red 14(400 mg/l) based on a Box-Behnken experimental design using an Electro-peroxone process for the remediation. Moreover, the influence of operational parameters was investigated in this study. Results: The results obtained from an Electro-peroxone process in a cylinder-shaped reactor showed 100% AR14 removal after 30 min with an initial dosage of dye at 400 mg/l at an optimum condition (Current intensity at 0. 7 A, pH at 10, reaction time at 30 min, and electrolyte concentration at 0. 1 M). Moreover, the removal percentage of the chemical oxygen demand was obtained at 69% after 30 min indicating the great performance of Electro-peroxone in the mineralization of AR14. Conclusion: The hydrogen peroxide is produced electrochemically from O2 in the O2-O3 mixture, which was entered into the reactor. Subsequently, the hydroxyl radicals were shaped via the peroxone reaction. Based on the high removal percentages of COD in short reaction time, it can be found that the Electro-peroxone process produces no secondary pollutants. Therefore, it can be regarded as an environmentally-friendly water treatment method.
