Abstract (en)
[origin: WO2005121408A2] The invention relates to a method for producing or regenerating persulfuric acid and the salts thereof by electrolysis of an aqueous solution containing sulfuric acid and/or metal sulfates on diamond-coated electrodes without using promoters. According to the inventive method, bipolar silicon electrodes are used which are diamond-coated on one side and whose uncoated silicon back is used as the cathode.
