Synthesis of chitosan derivatives bearing cyclodextrin and adsorption of p-nonylphenol and bisphenol A

An insoluble crosslinked chitosan bearing cyclodextrin moieties was prepared by a one-step procedure with N-succinylated chitosan and mono-6-amino-mono-6-deoxy-β-cyclodextrin in the presence of the water-soluble carbodiimide. The degree of substitution by the CD moiety achieved 0.27 with the addition of DMF to the reaction solution. The obtained material adsorbed bisphenol A quicker than p-nonylphenol.
