HYPOCHLOROUS ACID GENERATION METHOD AND APPARATUS FOR THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a hypochlorous acid generation method which is capable of efficiently generating hypochlorous acid by suppressing electric power consumption with a simple apparatus and the apparatus for the same. SOLUTION: The hypochlorous acid generation apparatus 10 has electrodes 13 and 14 disposed in a liquid for treatment within an electrolytic treating vessel 15 and an electric signal generator 11 for applying an electric signal between the electrodes. The electric signal generator 11 is constituted to generate such an electric signal which makes the electrode potential of the anode 13 higher than the electrochemical potential suitable for generation reaction of active radical species including hydroxy radicals or chlorine radicals and the electric signal which is any one of a DC component, pulse component or the component superposed with the DC component and the pulse component. The active radical species are generated by the electrochemical reaction based on the electric signal near the anode 13 in the liquid for treatment and the reaction field for generating the hypochlorous acid is formed by forming the intermediates of the hypochlorous acid from the active radical species and reacting the intermediates and oxygen.
