Sulfite-enhanced natural photodegradation of potassium butyl xanthate in mining wastewater: pH-dependent free radical species evolution and degradation pathways

Key Points

• Degradation pathways evolve under varying pH levels, revealing complex interactions in water systems.
• Key evidence shows that sulfite enhances the photodegradation, with significant transformations occurring at specific pH.
• The analysis uses observational data from mining wastewater samples, focusing on the roles of sulfite and free radicals.
• Highlights the need for further investigation into sulfite applications for treating mining wastewater.
