  • Method for separating metal ions
    Publication number: 20030108464
    Abstract: A method for separating metal ions, which comprises adding a selective capturing agent to an aqueous solution containing plural types of metal ions, said selective capturing agent being a cyclic compound and forming a complex with metal ions having ion radii suitable for the size of the ring alone, so that unnecessary metal ions are held by the selective capturing agent in the aqueous solution, and bringing said aqueous solution into contact with an ion exchange solid phase so as to transport desired metal ions alone to the solid phase.
