The objective of this study was to convert γ-cyclodextrin to a polymer and further to investigate the potential of using the polymer for the removal of methylene blue (MB) from aqueous solution. The sorption properties of γ-cyclodextrin polymer (γ-CDP) toward MB were investigated. The effects of contact time, sorption temperature and initial MB concentration were discussed. Batch sorption studies and kinetic studies have also been performed to understand the MB extraction ability of the γ-CDP. Results of experiments showed that γ-CDP exhibited some sorption capacities toward MB. It was found that kinetics followed Ho and McKay equation and isotherm fitted Langmuir model. The negative values of free energy change indicted the spontaneous nature of sorption.
