Tóm tắt

Per- and polyfluoroalkyl substances (PFAS) are a class of persistent organic compounds widely detected in the environments. Due to their chemical stability, physical adsorption has emerged as one of the most promising techniques for remediating PFAS-containing wastewater, while some newly synthesized functional absorbents in powder form suffer from separation issues. Inspired by mussel biology, we have successfully synthesized a porous spongy absorbent termed aminated polyurethane (PU-PDA-PANI) with over 99.5% removal efficiency for initial 10 mg L
