PURPOSE: To obtain the enhanced uptake power by reacting on a carrier a heterogiant cyclic compound having amino groups with an epoxy compound having a given molecular weight and a given number of epoxy groups.
CONSTITUTION: A heterogiant cyclic compound (A) having amino groups is reacted a carrier with an epoxy compound (B) having molecular weight of less than 10000 and at least two epoxy groups per molecule in the presence of an inorganic or organic salt (C) capable of forming a complex with said heterogiant cyclic compound, and then the inorganic or organic salt is eliminated. Alternatively, (A)-(C) adduct is reacted on a carrier with (B), and then the inorganic or organic salt is eliminated. For example, diaminodibenzo 18-crown-6. epoxy resin and Ki dissolved in dimethyl formamide is added to sellaite. The resulting product is heated, cured, washed with water, desalted and heated to 120°C to form fixed sellaite on the surface of which 1% as crown unit is carried.
