ABSTRACT:
A novel chelate resin is produced by causing a 2-hydroxybenzoic acid derivative to react upon a high molecular compound, i.e. a cross-linked polyethyleneimine or a cross-linked polyethyleneimine derivative, thereby linking a 2-hydroxybenzoyl group to the nitrogen atom in the imine chain of the high molecular compound. This chelate resin is capable of collecting, by adsorption and at high efficiency, such a metal as uranium dissolved in a trace amount in water.
