Separation method for a separation target metal

Abstract

A separation method for a separation target metal uses a metal ligand having an oxide of the separation target metal as a core. The separation method for the separation target metal includes a step of dispersing the metal ligand in a solution containing the separation target metal and separating the separation target metal in the solution as the oxide of the separation target metal. A metal coordination polymer includes: a metal oxide; and a ligand polymer that carries the metal oxide. The metal oxide is an oxide of any one, two, or more of cobalt, nickel, and manganese, and the ligand polymer is a copolymer of (1) an optionally substituted divinylbenzene and (2) acrylic acid or methacrylic acid.
