ABSTRACT:
An apparatus and method for the purification of liquids utilizing anodic oxidation wherein the electrodes are composed of an austenitic chromium-nickel-molybdenum steel which contains about 0.07% by weight carbon, more than about 17.0% by weight chromium, about 12.0 to 14.5% by weight nickel and about 2.5 to 4.5% by weight molybdenum. By using the electrodes of the present invention, one can avoid the precipitation of chromium which normally occurs during the purification processes of the prior art.
