(31g) Removal of Thiosulfate from Wastewater By Advance Oxidation Process

Thiosulfate is among the common pollutant present in the industrial wastewater, especially from industries like metal plating and mining and petrochemical present major environmental challenges. This research investigates the removal of thiosulfate from wastewater using advanced oxidation processes (AOPs). We explore several AOPs, including Fenton's reagent, ozonation and photocatalysis, under different conditions such as temperature, pH and reactant concentrations. The findings of research show that ozonation attains the highest thiosulfate removal efficiency, due to its fast reaction kinetics. Analytical methods, including ion chromatography, verify major reductions in thiosulfate levels and categorize oxidation by-products. Our findings depict the success of AOPs in treating thiosulfate-laden wastewater, proposing their potential integration into existing treatment systems. This research supports the growth of more sustainable wastewater management approaches, tackling both regulatory compliance and environmental protection. Future research will put attention on improving these processes for large-scale applications.
