Beta-cyclodextrin-linked chitosan beads: preparation and application to removal of bisphenol A from water.
Water-insoluble and highly porous chitosan beads having an ability to form inclusion complexes have been synthesized by treatment of a solution of chitosan in aqueous acetic acid with aqueous NaOH followed by crosslinking and reductive alkylation with 2-O-formylmethyl-beta-cyclodextrin. Preliminary experiments for its application to removal of endocrine disrupting chemicals were carried out using a column of the resulting beads and bisphenol A as the model substrate.
