  • Immobilized extractants
    Patent number: 4711863
    Abstract: A process for the production of a solid, particulate immobilized extractant, which process comprises adsorbing (a) a liquid extractant which is not homopolymerizable onto (b) a porous, solid, particulate, substrate; adsorbing (c) a monomer onto the substrate; and polymerizing the adsorbed monomer (c) thereby entrapping the liquid extractant (a) on substrate (b).
    Type: Grant
    Filed: March 10, 1986
    Date of Patent: December 8, 1987
    Assignee: National Research Development Corporation
    Inventors: Michael Streat, Sofia Belfer-Canterman
  • Ion exchange materials
    Patent number: 4130512
    Abstract: A process for the production of a particulate ion exchange material which comprises heating an inorganic material to produce a porous inert inorganic substrate, adsorbing an organic monomer into the substrate and polymerizing the adsorbed monomer so that the resultant polymer is retained within the pores of the substrate, and, if necessary, introducing ion exchange functional groups into the polymer.
