Embodiment 1
[0103] make KClO 3 Dissolved in pure water.
[0104] in the KClO 3 Citric acid was added to the aqueous solution. Thus, the pH was adjusted to about 4.
[0105] Determine the KClO of this pH4 3 The residual chlorine concentration of the aqueous solution.
[0106] In addition, KClO at pH 4 above 3 Add H to the aqueous solution 2 O 2 The aqueous solution was used to measure the residual chlorine concentration.
[0107] The results of this measurement (measured by the KI method) are shown in Table-1 below.

[0110] Elapsed time Concentration (ppm)
[0111] Potassium Chlorate 125 125 125 125 125 125
[0112] Hydrogen Perchloride 0 30 60 120 240 480
[0113] Residual chlorine 0 days 0 5 25 30 30 125

[0116] 30 days 0 200 250 300 300 350
[0117] It can be seen from this Table-1 that by containing H 2 O 2 , even ...
Embodiment 2
[0120] make KClO 3 Dissolved in pure water.
[0121] in the KClO 3 Citric acid was added to the aqueous solution. Thus, the pH was adjusted to about 4.
[0122] in the KClO 3 NaClO was further added to the aqueous solution.
[0123] Then, the residual chlorine concentration was measured. The results were not significantly different from the case of the NaClO aqueous solution.
[0124] Then, use figure 1 The anodic electrolyzed water produced in the illustrated two-chamber type electrolytic cell replaces the above-mentioned pure water. The two-chamber electrolytic cell is as follows: a platinum electrode made of an 80-mesh mesh (the size of the electrode is 80mm × 60mm) is used as the anode electrode, a titanium electrode (the size of the electrode is 80mm × 60mm) is used as the cathode electrode, and a fluorine-based cation exchange membrane is used as the A membrane separating the anodic and cathodic compartments. Then, pure water is supplied to the cathode chamber a...
Embodiment 3
[0129] Dissolve 40ppm NaClO and 100ppm KClO in the anode electrolyzed water of Example 2 2 . Further addition of citric acid adjusted the pH to about 6.
[0130] Determination of the content of NaClO and KCIO 2 The residual chlorine concentration of the aqueous solution (measured by the KI method), the results are shown in Figure 8 .
[0131] by the Figure 8 It can be seen that the long-term high retention of NaClO and KClO 2 the residual chlorine concentration of the aqueous solution.
