Abstract
A method for producing a weakly acidic hypochlorous acid aqueous solution comprises (A) an ion-exchange step for generating molecular hypochlorous acid dissolved in a mixed solution by mixing a raw material aqueous solution composed of an aqueous solution of a metal salt of hypochlorous acid with an acidic ion-exchange resin to perform ion exchange between the metal ions and the hydrogen ions, and (B) a separation step for separating the acidic ion-exchange resin from the mixed solution after the ion-exchange step and obtaining weakly acidic hypochlorous acid aqueous solution in which molecular hypochlorous acid is dissolved.
