Abstract
En 中文
• A three-dimensional COF/CS aerogel was fabricated by vacuum freeze-drying. • The COF/CS aerogel achieved 88% removal of polystyrene microplastics within 2 h, significantly higher than that of pristine CS aerogel (51%). • The COF/CS aerogel maintained a removal efficiency of 93% after five adsorption-desorption cycles. • Effective PSMPs removal was maintained across a broad pH range and in complex water matrices. • Dual-action capture: physical entrapment (macroporous chitosan) and chemical anchoring (π-π stacking, hydrophobic, H-bonding).
