UV-induced aging creates adsorption hotspots: Oxygen-containing functional groups on nanoplastics dictate the adsorption behavior of ciprofloxacin

Key Points

• Adsorption hotspots emerge from UV-induced aging, enhancing interactions with ciprofloxacin.
• The presence of oxygen-containing functional groups significantly alters the adsorption behavior observed.
• Analysis used nanoplastics to investigate the impact of UV aging on ciprofloxacin adsorption.
• Findings suggest potential implications for environmental contamination management and pollutant transport.
