The Adsorption of Chitosan-Aluminum Oxide Composite Material to Mercury Ions

Abstract:

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 Hg²⁺ had been greatly improved better than the mixture of chitosan and Al₂O₃ materials and chitosan .the adsorption rate of Hg²⁺was 18% higher than that of chitosan, adsorption capacity is up to 900mg/g.
