Abstract
Oxidizable contaminants in waters, such as feed waters and waste waters wherein they are present in relatively large or small proportions, are removed therefrom by alternating current electrolysis in an electrolytic cell containing catalyst-containing particles, the catalyst of which is an oxidation catalyst such as MnO.sub.2, Cr.sub.2 O.sub.3, Bi.sub.2 O.sub.3, or PbO.sub.2. The process and apparatus of the invention are especially useful for the removal of difficultly oxidizable impurities, such as phenol, from dilute aqueous solutions or dispersions. Included within the invention is the improved removal of such impurities by sequential treatments in accordance with the described processes. Also disclosed are the production of hydrogen peroxide by alternating current electrolysis of water; the oxidation of phenolic compounds; the reactivation of at least partially inactivated carbon adsorbents by subjection to alternating current; and the concentration of chemical impurities from activated carbon by adsorption on particles thereof, followed by desorption by application by alternating current.
