  • Method for purifying industrial waste water by direct oxidation of the organic pollutants
    Patent number: 4839007
    Abstract: A method for purifying industrial waste water by direct oxidation of the organic pollutants in an electrochemical cell the anode of which contains, in its active part or in any intermediate layer present, neither noble metals in any form nor PbO.sub.2 nor graphite, but instead comprises in this part exclusively SnO.sub.2 which is doped with F, Cl, Sb, Mo, W, Nb, Ta or with a mixture of at least two of these elements. The anode has an oxygen overvoltage which is higher than that of a PbO.sub.2 comparison anode and reaches the value of at least 1.85 V at a current density of 0.1 mA/cm.sup.2 in 1 normal H.sub.2 SO.sub.4 under a pressure of 1 bar at a temperature of 20.degree. C. in the presence of a Pt counterelectrode.
