Double sulfuration promotes the activation of peroxydisulfate by Fe-based N/S co-doped biochar composites to degrade sulfapyridine: Synergistic effect and degradation mechanism

Key Points

• Double sulfuration significantly enhances the activation of peroxydisulfate, leading to improved degradation rates.
• The interaction between iron and sulfur in biochar composites contributes to an effective decomposition mechanism for sulfapyridine.
• Analysis of biochar composite interactions suggests strong potential for application in environmental remediation technologies.
• Environmental implications suggest that using such composites may offer new strategies for pollutant degradation in contaminated sites.
