ION EXCHANGE RESIN AND METHOD OF ADSORPTION SEPARATION OF METAL

摘要

PROBLEM TO BE SOLVED: To provide a system for efficiently recovering a trace metal from a large amount of raw material, such as recovering a trace metal from nickel oxide ore.SOLUTION: The ion exchange resin of the invention comprises on a support an amide derivative represented by the following general formula, wherein each of Rand Rrefers to the same or different alkyl group; Rrefers to a hydrogen atom or an alkyl group; and Rrefers to a hydrogen atom or any group other than an amino group that is attached to an α carbon as an amino acid. The amide derivative is preferably a glycinamide derivative. The support preferably includes a primary amine and/or a secondary amine.
