  • ELECTROCHEMICAL REMOVAL OF ARSENIC
    Publication number: 20170225991
    Abstract: The present invention provides for a system for removing arsenic from an arsenic contaminated aqueous solution, and its use thereof. The system comprises an anode comprising iron and a cathode comprising iron or an electricity conducting metal that is electropositive relative to iron in contact with the arsenic contaminated aqueous solution. The system is used by running an electric current through the water via the anode and cathode to cause the formation of iron (hydr)oxide from the iron of the anode which then forms an insoluble arsenic-iron (hydr)oxide complex which can be separated from the aqueous solution.
