Porous structured chitosan–β-cyclodextrin membranes were synthesized by incorporating β-cyclodextrin polymers as the functional reagent and using γ-glycidoxypropyltrimethoxysilane as crosslinking agent. Compared with chitosan itself, the synthesized membranes showed significant changes in the molecular constitutions, crystalline and thermal properties. It was found that the mol ratio of the epoxy...
Glutaraldehyde activated chitosan beads bearing β-cyclodextrin cross-linked by 1,6-hexamethylene diisocyanate was prepared, and characterized by IR, XRD and TG-DTA. Its adsorption property of hydroquinone was investigated by spectrophotometry. The adsorption capacity increases with increasing temperature and pH value. The adsorption process can be better simulated by Freundlich isotherm equation (R2>0...
