Abstract: Cyclodextrin epichlorohydrin cross-linked polymers modified with diethylamine,ethylene diamine and diethylene triamine were prepared under controlled conditions.Adsorption abilities of the modified polymers for o,p-nitrophenol were enhanced while selectivity for the structural isomers had not been found in the literatures, Adsorption behavior conformed to Freundlich isotherm equation and equilibrium constants were evaluated.Enhanced adsorption abilities were explained as a result of the additional acid base interaction besides inclusion.

Key words: Cyclodextrin, β-Cyclodextrin resin, Amino modifying, Selective adsorption, Adsorption equilibrium constants
