PROBLEM TO BE SOLVED: To generate a stabilized aq. hypochlorous acid soln. excellent in sterilizing property by supplying only an aq.soln. of the chloride of sodium, potassium or an alkaline-earth metal to an electrolytic cell and to provide the electrolytic method and device by which the contents of the remaining sodium chloride, etc., are drastically decreased. SOLUTION: This sterilizing electrolytic water is produced by electrolyzing an aq. sodium chloride soln. in a diaphragm-less electrolytic cell, then introducing the formed electrolyte on the anode side of a diaphragm electrolytic cell or further introducing an aq. sodium chloride soln. into the diaphragm electrolytic cell and electrolyzing the soln. to incorporate hypochlorous acid into the soln. The electroytic water thus obtained is preferably controlled to pH 6.0-7.5, and the concn. of effective chlorine is controlled to 1-40 ppm. |
