Sudan black B dye degradation in aqueous solution by Fenton oxidation process: Kinetics and cost analysis

The presence of dyes in effluents discharged from the textile industries is one of the major concerns of water-living organisms. This study aimed at investigating the Fenton degradation of Sudan black B (SBB) dye in an aqueous solution. The effects of initial dye concentration, Fe2+ concentration, and H2O2 concentration were evaluated based on the removal of color and dye from the solution. Operating costs and kinetics study of the Fenton process were assessed. The optimum conditions were determined as [Fe2+] of 150 mg.L−1, [H2O2] of 100 mg.L−1, and a reaction time of 30 min. Dye and color removals for the different combinations of the process were on average > 80% and >75%, respectively. However, the process was not effective for…
