  • Immobilization of inorganic arsenic species using iron
    Patent number: 6387276
    Abstract: A method for the remediation of arsenic is presented, comprising providing an aqueous solution of inorganic arsenic species, and passing the solution of inorganic arsenic species over a substrate comprising zero valent iron under anaerobic conditions, thereby reducing the arsenic species and forming arsenic-metal co-precipitates. Preferably, the metal is iron in the form of iron filings, and a source of sulfate ions is also present, resulting in the precipitation of arseno-pyrites.
    Type: Grant

  • Immobilization of inorganic arsenic species using iron
    Patent number: 6132623
    Abstract: In a method for the remediation of inorganic arsenic species, a solution of inorganic arsenic is passed over zero valent iron under abiotic and anaerobic conditions, thereby removing the inorganic arsenic species and forming arsenic-metal co-precipitates. The metal is preferably in the form of iron filings, and is provided together with sand.
