A simple chemical bonding method to synthesize magnetic cyclodextrin-chitosan/graphene oxide (CCGO) was reported. The adsorption behaviors of Cr(VI) in aqueous solution on CCGO were systematically investigated. As the results shown that, with the advantage of high surface area, abundant hydroxyl and amino groups of CCGO, and the magnetic property of Fe3O4, the Cr(VI) can be easily and rapidly extracted from the water by magnetic attraction under investigation. The adsorption equilibrium of CCGO for Cr(VI) corresponded with Langmuir isotherm, and the novel adsorbent exhibited better Cr(VI) removal efficiency in solutions with low pH. It was found that the Cr(VI) adsorption performance of CCGO strongly depends on their surface charge concentration and specific surface area. These results provide evidences for estimating and optimizing the removal of metal ions from the wastewater by using of CCGO composites in the future. |
