Polyacrylic acid-mediated sulfamethoxazole degradation by hydroxyl radicals during FeS oxidation under aerobic conditions

Key Points

• Sulfamethoxazole degradation is significantly enhanced through polyacrylic acid-mediated processes.
• Hydroxyl radicals generated during FeS oxidation play a crucial role in the degradation process.
• Analysis of degradation processes indicates a positive correlation between polysaccharide concentration and pollutant removal efficiency.
• Implications highlight the potential of using polyacrylic acid in wastewater treatment systems for better pollutant management.
