Chitosan@Fe3O4 material was successfully synthesized by a ball milling method and characterized. The material was used for the removal of dye CR, and the adsorption behavior and recycling performance were studied.
Chitosan and Fe3O4 were used as raw materials to successfully synthesize Chitosan@Fe3O4 by a simple, green and friendly solvent-free ball milling method. The surface morphology, phase composition, structure and magnetic properties of the Chitosan@Fe3O4 material were characterized using SEM, FT-IR, XRD, VSM methods. The prepared material was used as an adsorbent to remove the target congo red (CR) dye. The effect of experimental factors such as solution pH and contact time on the adsorption performance were studied and optimized. The adsorption behavior of Chitosan@Fe3O4 material for CR dye was investigated, and the adsorption mechanism, recycling performance of the materials were discussed.
