1. A method for removing oxidizable organic compounds from an aqueous solution comprising:

  • a) introducing an aqueous solution containing oxidizable organic compounds into an anodic chamber of a solid polymer electrolyte electrolysis cell said cell having an anode, a cathode, and a cathode chamber wherein a metal catalyst is positioned on the surface of the anode;

    b) applying an absorption potential to the anode of the electrolysis cell sufficient to cause the oxidizable organic compounds to absorb onto the surface of the anode;

    c) applying an oxidation potential to the anode sufficient to oxidize said absorbed oxidizable organic compounds and thereby produce carbon dioxide and hydrogen gas and forming a metal oxide layer on the anode catalyst;

    d) applying a regenerating potential to the anode sufficient to reduce the metal oxide layer formed on the anode catalyst to the non-oxidized metal catalyst state.
