関係する。By the way, in such a method for producing electrolytically produced water, when the electrolytic cell is operated for a long time, the available chlorine amount of the produced water on the anode chamber side, pH, and the oxidation of the produced water on the cathode chamber side are oxidized. The characteristics of the electrolytically generated water, such as the reduction potential, gradually decrease. One of the causes of the deterioration of the characteristics of the electrolytically generated water is the consumption and deterioration of the noble metal coating on the surface of the electrodes arranged in each chamber of the electrolytic cell. This deterioration phenomenon is caused by platinum containing iridium. -It is particularly remarkable in an electrode having an iridium-based fired coating. The electrode has an advantage that it is extremely advantageous for producing available chlorine, but is consumed and deteriorated by switching positive and negative applied voltages to both electrodes for removing scale adhering to the electrode during electrolysis. By switching the polarity of the printing voltage of the electrodes, a reaction occurs in which iridium oxide is ionized through iridium, and this reaction consumes the coating of each electrode,
It will deteriorate. Therefore, the consumption and deterioration of the electrode coating are related to the number of times the polarity of the applied voltage is switched, and when the polarity is switched regularly, it is related to the operating time of the electrolytic cell.
