Electrodes structure for high concentration hypochlrous acid solution from soidum chloride solution and method for manufacturing sterilized water using the same

摘要

PURPOSE: An electrodes structure for a high concentration hypochlrous acid solution from a sodium chloride solution and a method for manufacturing sterilized water using the same are provided to suppress adhering of a salt to an electrode and to have a low tendency in order to extract a metallic component of the electrode in sterilizing water. CONSTITUTION: An electrodes structure for a high concentration hypochlrous acid solution from a sodium chloride solution and a method for manufacturing sterilized water using the same comprise the following steps: An aqueous solution of a slightly acid is obtained by dissolving and injecting an additive composition for sterilization including a sodium chloride and an organic acid into water within an electrolytic cell(S21); A titanium electrode coated with an Iridium oxide is an anode electrode and a titanium electrode is a cathode electrode. A DC voltage is applied in an electrode structure in which the anode electrode and cathode electrode is faced with each other. The aqueous solution of the slightly acid is electrolyzed in the electrolytic cell(S22); The DC voltage applied in the electrode structure is blocked when hypochlorous acid sterilizing water which is pH4.5-6.5 and in which an amount of remaining chlorine is 10-200ppm is generated by electrolyzing the aqueous solution of the slightly acid(S24). [Reference numerals] (AA) Start; (BB) End; (S21) Obtain a slightly acid aqueous solution by putting and dissolving a sterilizing additive composition, which is prepared in a powder or tablet form by mixing bay salt and organic acid powder so that 80-98wt% of sodium chloride and 2-20wt% of organic acid according to the electric conductivity of water to be made into sterilized water are mixed, in the water in an electrolytic cell; (S22) Apply a DC voltage to an electrode structure submerged in the slightly acid sodium chloride aqueous solution in the electrolytic cell, using a titanium electrode coated with iridium oxide as an anode electrode and a titanium electrode as a cathode electrode; (S23) Receive one or more among a user preference time, the amount of the sterilizing additive composition, the amount of water, the kind of water, and a desired pH, which are inputted from a user; (S24) Block the DC voltage being applied to the electrode structure when a time determined according to one or more of the input conditions or a time predetermined as default has passed
