• Novel adsorbents that are composed of ligand, spacer and support were chemically synthesized and the two consecutive screenings of them made it possible to determine the adsorbents that were most recommendable for α- and β-cyclodextrin(CD)production. First, ligands of high adsorption selectivity for each CD were screened from among the candidates(carbozylic acids)that are tied in ionic bonds to two types of strongly basic anion exchange resins as support. Secondly, ligand dericatives(as ligand and spacer)were bound in covalent bonds onto chitosan beads as support and then, the most suitable spacer length for the CD's adsorption selectivity and capacity were investigated. An optimal mol ratio of ligand to amino group of the beads was also examined. Stearic acid was the most effective ligand for α-CD, whereas cyclohyxanepropanamide-n-caproic acid was the best for β-CD. Adsorption selectivity of adsorbents derived from carboxylic acids(stearic and/or palmitic)and chitosan beads was almost 100%, while their adsorption capacities were large enough to meet the demand for economic production and purification of CDs on an industrial scale.
