  • COMPOSITION FOR REMOVING ARSENIC FROM AQUEOUS STREAMS
    Publication number: 20080093580
    Abstract: Arsenic is removed from water and other aqueous feeds by (1) treating the feed with a compound containing cerium in the +4 oxidation state, preferably cerium dioxide, to oxidize arsenic in the +3 oxidation state to arsenic in the +5 oxidation state and (2) removing the arsenic in the +5 oxidation state from the aqueous phase, normally by contacting the treated feed with alumina or other precipitating agent containing cations in the +3 oxidation state.
    Type: Application
    Filed: October 26, 2007
    Publication date: April 24, 2008
    Inventors: Richard Witham, Edward McNew, John Burba
