Ion exchange resin and method for adsorbing and separating metal

摘要

Provided is a system for efficiently recovering trace metal from a large amount of a raw material, such as when trace metal is recovered from nickel oxide ore. This ion exchange resin has, on a carrier, an amide derivative represented by the following general formula. In the formula, R1 and R2 represent the same or different alkyl groups, R3 represents a hydrogen atom or an alkyl group, and R4 represents a hydrogen atom or an arbitrary group, other than an amino group, bonded to α carbon as an amino acid. The amide derivative is preferably a glycineamide derivative. The carrier preferably includes a primary amine and/or a secondary amine.
