Abstract
The method includes a process of (i) and a process of (ii) in this order. In the process of (i), the potential of a first anode and the potential of a first cathode are adjusted in an aqueous solution containing chloride ions so as to increase the concentration of free chlorine in the aqueous solution. In the process of (ii), the potential of a second anode and the potential of a second cathode are adjusted in the aqueous solution so as to decrease the concentration of free chlorine in the aqueous solution. The difference between the potential of the second anode and the potential of the second cathode in the process of (ii) is smaller than the difference between the potential of the first anode and the potential of the first cathode in the process of (i).
