Application of Optimized Photo-Fenton Process for The Degradation of Allura Red Dye in Process Textile Waste water

Abstract

This study, presents an optimized photo-Fenton process degradation of Allura red dye from textile process industrial wastewater, by the determination of optimal conditions for the photo-Fenton process to achieve maximum Allura red degradation. Water scarcity is a critical challenge and a cornerstone of sustainable progress. Meeting the growing demand for drinking water is essential for modern societal development. The photo-Fenton process is an effective method for the degradation of organic pollutants and dyes in wastewater. The effects of different parameters such as pH, concentration of hydrogen peroxide, concentration of iron (III) ions, and initial dye concentration on the degradation efficiency were investigated. A central composite design (CCD) was used to determine the optimal values of the parameters. The results showed that the maximum degradation of Allura red dye (96%) was achieved at pH 3.5, hydrogen peroxide concentration of 0.1 M, iron (III) ion concentration of 0.005 M, and initial dye concentration of 25 mg/. The mineralization of the dye was evaluated by measuring the total organic carbon (TOC) removal. The maximum TOC removal was found to be 76.2%. Therefore, the optimized photo-Fenton process was considered a promising method for the removal of Allura red dye from textile industry wastewater. The experimental model generated precise equations, providing valuable insights into the degradation process.
