A water-insoluble beta-cyclodextrin (beta-CD) polymer was synthesized by reacting beta-CD with hexamethylene diisocyanate, and its adsorption kinetics and thermodynamics for phenol from aqueous solution was investigated. The kinetics of adsorption followed the pseudo-second-order model and the adsorption isotherms could be well fitted by the Freundlich adsorption equation. The values of thermodynamic parameters demonstrated that the adsorption was a physisorption in a spontaneous and exothermic process.
