Arrangement for the purification of liquids by means of anodic oxidation

摘要

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.
