Cover Story: A novel phosphorus-modified magnetic chitosan adsorbent (PCC/Fe3O4) was synthesized using Fe3O4 as the core and tetrakis hydroxymethyl phosphonium sulfate (THPS) as a cross-linking agent. The composite exhibited a high surface area (20.67 m2/g) and superparamagnetism, enabling easy magnetic recovery. PCC/Fe3O4 demonstrated superior Cr(VI) removal capabilities compared to unmodified chitosan and raw Fe3O4, achieving a saturated adsorption capacity of 23.6 mg/g under the selected conditions (pH 6, initial Cr(VI) concentration of 1 mg/L). The main removal mechanism includes electrostatic attraction, redox reaction, and ligand exchange. PCC/Fe3O4 maintained 86% efficiency after 5 d aging and >90% efficiency after five cycles, demonstrating both excellent stability and reusability and strong potential for practical environmental remediation.
