  • Solid materials for removing arsenic and method thereof
    Patent number: 7803737
    Abstract: Solid materials have been developed to remove arsenic compounds from aqueous media. The arsenic is removed by passing the aqueous phase through the solid materials which can be in molded, granular, or powder form. The solid materials adsorb the arsenic leaving a purified aqueous stream. The materials are aerogels or xerogels and aerogels or xerogels and solid support structure, e.g., granulated activated carbon (GAC), mixtures. The species-specific adsorption occurs through specific chemical modifications of the solids tailored towards arsenic.
    Type: Grant
    Filed: June 6, 2008
    Date of Patent: September 28, 2010
    Assignee: Lawrence Livermore National Security, LLC
    Inventors: Paul R. Coronado, Sabre J. Coleman, Robert D. Sanner, Victoria L. Dias, John G. Reynolds
