DOM-mediated inhibition of ciprofloxacin photodegradation: Dual roles of antioxidant quenching and triplet-state interactions

Key Points

• Ciprofloxacin photodegradation significantly reduces when influenced by dissolved organic matter.
• Antioxidant quenching plays a key role, alongside triplet-state interactions in this process.
• Analysis incorporated various DOM types and environmental conditions to assess their impact on ciprofloxacin stability.
• These findings may enable improved management of pharmaceutical pollutants in aquatic systems.
