PURPOSE:To impart to cyclodextrin immobilized by a resin insoluble in a solvent a function for recognizing hydrophobic group and a function for recognizing functional group by introducing a primary amino group to a primary OH group side of said cyclodextrin. CONSTITUTION:Immobilized cyclodextrin such as copolymer of cyclodextrin with epichlorohydrin, etc. is swollen and is allowed to react with p-toluene sulphonyl chloride in an inert solvent, then, the reaction product is allowed to react with ethylenediamine, aminoethane thiol, or ammonia, etc., and then washed with alakaline aq. soln. such as aq. soln. of caustic soda, etc., to introduce a primary amino group to immobilized cyclodextrin. Then, the cyclodextrin having introduced primary amino group is allowed to react with an insoluble high molecular substance having ester groups such as crosslinked polymethyl acrylate, crosslinked polyethyl acrylate, etc.
