  • Methods of preparing a surface-activated titanium oxide product and of using same in water treatment processes
    Patent number: 7497952
    Abstract: A method for removing dissolved contaminants from solution using a surface-activated crystalline titanium oxide product having a high adsorptive capacity and a high rate of adsorption with respect to dissolved contaminants, in particular, arsenate and arsenite. Preferably, the titanium oxide product includes crystalline anatase having primary crystallite diameters in the range of 1-30 nm. The surface-activated titanium oxide is combined with other filter media to further improve the removal of dissolved contaminants.
    Type: Grant
    Filed: July 7, 2005
    Date of Patent: March 3, 2009
    Assignee: The Trustees of Stevens Institute of Technology
