The sorption of beta-cyclodextrin polymer (beta-CDP) and gamma-cyclodextrin polymer (gamma-CDP) toward 2,4-dichlorophenol (2,4-DCP) in aqueous solutions was investigated. The influence of sorption conditions including initial 2,4-DCP concentration, contact time and pH on sorption capability were discussed. Their sorption behaviors for 2,4-DCP were conducted and it was found the sorption kinetics followed the Ho and McKay equation and the film diffusion was the rate-determined step. The sorption isotherm can be correlated to Freundlich model and the sorption capacity on beta-CDP was much larger than that on gamma-CDP. The maximum sorption capacity of 2,4-DCP for beta-CDP was measured to be 0.16 mmol/g with the initial concentration at 0.67 mmol/L at 288 K. The CDPs were easily recovered by ethanol as washing solvent and they could be used as a kind of recyclable sorbents.
