Abstract: Adsorption model of metal ion on imprinting chitosan resin was studied. The chemical and the physical properties such as pore size distribution and heat stability were discussed and the imprinting chitosan resin can be used many times without losing adsorption capacity. The adsorption isotherms and adsorption mechanism were studied and a new model was suggested to correlate relation of adsorption with pH and metal ion concentration,which could explain mechanism of adsorption.
