ABSTRACT:
The invention relates to a method and an electrochemical device capable of producing very pure oxygen. Air is made to react with a reduced form of anthraquinone 2-7 sodium disulphonate in order to obtain a peroxide of this compound which decomposes to an oxidized form and to hydrogen peroxide or water depending on the pH value of the medium, said hydrogen peroxide being decomposed to water, and the water being electrochemically oxidized thus releasing the oxygen, while said oxidized form is electrochemically reduced. The invention is used for the production of very pure oxygen suitable for purifying used water.
