Well-designed chitosan-based cationic porous polymer: A robust material for effective adsorption of endocrine disrupting chemicals

Year: 2024

Type: article

Abstract: There is an immediate need for meticulous design of easily accessible, cost-effective, chemically stable and eco-friendly materials for effectively removal of water contaminant. Herein, targeting typical water contaminants, endocrine disrupting chemicals (EDCs), three cationic hyper-cross-linked porous polymers (ciHCP-1, ciHCP-2, ciHCP-3) with multiple adsorption sites were designed with 2-hydroxypropyltrimethyl ammonium chloride chitosan (HACC) as precursor. The ciHCP-3 with large surface area (806 m 2 g −1 ) exhibited high sorption capacity (137–366 mg g −1 ), and fast adsorption kinetics (5 min) for the EDCs, which is superior to the reported sorbents . The adsorption mechanisms can be attributed to the synergistic effect of physisorption and chemisorption . The high preparation reproducibility, physicochemical stability, and reuse capability of ciHCP highlights its great potential in practical water remediation applications.
