The Adsorption of Zn²⁺ onto Chitosan-Aluminum Oxide Composite Material

Abstract:

Chitosan-aluminum oxide composite material was synthesized through chemical bonds with chitosan and isopropanol aluminum as raw material, whose structure was characterized by IR, TG. 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 thermal stability of the composites is improved significantly. Chitosan-aluminum oxide composite material has good adsorption performance of Zn²⁺ in solution. The adsorption quantity of Zn²⁺ increases with the increasing of the adsorption temperature and the adsorption time, and the best adsorption time is 7.0h.
