Preparation and adsorption properties of magnetic chitosan/sludge biochar composites for removal of Cu²⁺ ions.

ABSTRACT: The magnetic chitosan/sludge biochar composite adsorbent was prepared using chitosan, Fe₃O₄, and sludge biochar as raw materials. The composite adsorbent was able to achieve rapid solid-liquid separation under an applied magnetic field. The morphology and microstructure of the composite adsorbent were characterized by FTIR, XRD, SEM, VSM, and BET analysis. The adsorption performance of the composite adsorbent on Cu²⁺ was investigated through static adsorption experiments, and the effects of adsorbent dosage, initial concentration of Cu²⁺, initial pH of the solution, and adsorption temperature on the adsorption efficiency of Cu²⁺ were discussed. The results showed that chitosan and Fe₃O₄ were successfully loaded on
