The Adsorption of Cu2+ onto Chitosan-Aluminium Oxide Composite Material
Chitosan-aluminum oxide composite material was synthesized through chemical bonds with chitosan and isopropanol aluminum as raw material, whose structure was characterized by SEM. The influence of reaction conditions on adsorption performance were studied, such as temperature, time. Results show that in the composite materials, chemical bonds were existed between aluminum and chitosan, inorganic aluminum oxide evenly dispersed in the surface of chitosan molecular. The adsorption capacity of such composite towards Cu2+ had been greatly improved better than the mixture of chitosan and Al2O3 materials and chitosan .the adsorption rate of Cu2+ was 13% higher than that of chitosan, adsorption capacity is up to 146 mg/g.
