Abstract
The present invention relates to a method for simultaneous continuous-action production of alkali metal or ammonium peroxodisulphate salts and alkali metal hydroxide. The electrolytic phase of the method is performed in a three-space electrolytic cell (1), into the middle space (3) whereof alkali metal sulphate is conducted, into the anode space (4), ammonium or alkalimetal sulphate, or a mixture thereof is conducted, and into the cathode space (2), water or diluted alkali metal hydroxide is conducted. Direct current is conducted through the electrolytic cell (1), whereby the sulphate ions pass into the anode space (4) and are oxidized into peroxodisulphate ions, thus producing alkali metal or ammonium peroxodisulphate, which is transformed into saline form in a fashion known in itself in the art, and the alkali metal ions pass into the cathode space (2) and form alkali metal hydroxide.
