  • Patent number: 4083782
    Abstract: Water is conditioned by contacting it with a weak acid cation exchange resin based upon a crosslinked methacrylic acid copolymer structure in the alkali metal (or ammonium) form. The resin when exhausted may be regenerated by either a two-step acid/alkali technique or by a one-step technique using a citric or fumaric acid solution or a poly or hexamethaphosphate solution. Water by this method is substantially free of hardness ion, dissolved heavy metal ions and has a corrected pH between 7 and 9.5, preferably between 8 and 8.5.

  • Patent number: 4064042
    Abstract: Partially pyrolyzed particles of macroporous resinous polymer have improved structural stability and utility. Pyrolyzed preformed beads are useful as adsorbents in both gaseous and liquid media to remove impurities such as vinylchloride monomer from gases, aromatic compounds such as barbituates from blood, and phenolics from industrial waste streams. Pyrolyzed materials are also useful as catalysts in industrial and laboratory applications due to the controllable surface area and due to a variety of metals, among other things, that may be incorporated into the particles prior to pyrolysis. Preferred adsorbents are prepared from pyrolyzed beads of macroreticular ion exchange resins.
