  • Patent number: 7041262
    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.
    Type: Grant
    Filed: December 12, 2002
    Date of Patent: May 9, 2006
    Assignee: National Institute for Research in Inorganic Materials
    Inventors: Yu Komatsu, Shigekazu Tsurubou

  • Patent number: 5066404
    Abstract: A method for separating sodium and potassium from an aqueous solution containing such metals, which comprises selectively ion-exchanging sodium and potassium with titania hydrate (TiO.sub.2 .multidot.nH.sub.2 O where n=1 to 2) obtained by treating potassium titanate to remove potassium therefrom, followed by a reaction at a temperature of from 25.degree. to 80.degree. C. to desorb and purify sodium and potassium.
