Abstract

The invention relates to an electrode suitable for decreasing the chemical oxygen demand of waste water comprising: a) a permanent component; and b) a sacrificial component arranged face to face and releasably attached to the permanent component and in electrical contact therewith said permanent component consisting of a Substrate of a valve metal equipped with a catalytic coating containing noble metals or oxides thereof said sacrificial component containing elemental iron. Further the invention relates to a method for abatement of the chemical oxygen demand in an aqueous waste containing oily compounds glycols or waxes optionally consisting of a foundry waste by an electrolytic process involving anodic chlorine evolution in the presence of trivalent iron. Chlorine evolution may be carried out on the surface of an anode consisting of a catalytically activated valve metal permanent component coupled to an iron containing sacrificial component.
