  • Apparatus for treating a flow of an aqueous solution containing arsenic
    Patent number: 8066874
    Abstract: An apparatus for treating an aqueous solution containing arsenic. The apparatus comprises a container that includes a housing, an inlet located at a first end of the housing and an outlet located at a second end opposite the first end. An outer wall extends between the first and second ends and enclosing a fluid flow path between the inlet and the outlet and an arsenic fixing agent is disposed in the fluid flow path. The arsenic fixing agent can include an insoluble rare earth-containing compound, more specifically, a compound comprising one or more of cerium, lanthanum, or praseodymium. The inlet and the outlet are adapted to be closed during transport and storage. The container is adapted to be sealed for long term disposal after exposure to an aqueous solution containing arsenic.
