PROBLEM TO BE SOLVED: To provide a method of capable of quickly producing a uniform halogen dioxide aqueous solution, preferably chlorous acid, from a halogen dioxide salt aqueous solution, preferably chlorite, and capable of using steam converted from the halogen dioxide aqueous solution by a pump of smaller output.SOLUTION: In a method of producing an aqueous solution containing halogen dioxide, an aqueous solution containing a halogen dioxide salt, preferably chlorite, is poured into a container 3 having electrodes 5, 6 from a storage tank 1 by a pump 2, an electric current is made to flow between the electrodes from an AC power supply device 4 to convert the halogen dioxide salt into a halogen dioxide, and an aqueous solution containing the halogen dioxide is made to flow out from a nozzle 7. The supplied aqueous solution contains a halogen dioxide salt in a concentration of at least 1 ppm. The produced aqueous solution contains a halogen dioxide in a concentration of 0.5-5,000 ppm, preferably 1-500 ppm. Two or three electrodes are provided in the container for increasing pressure by steam generation, to which 100-230 V single-phase or three-phase alternating current is supplied, and a halogen dioxide-containing aqueous solution is produced.COPYRIGHT: (C)2016,JPO&INPIT【課題】二酸化ハロゲン塩水溶液好ましくは亜塩素酸塩から、均一な二酸化ハロゲン水溶液好ましくは亜塩素酸を迅速に製造でき、より小さな出力のポンプで前記水溶液を水蒸気にして使用できる方法の提供。【解決手段】二酸化ハロゲン塩好ましくは亜塩素酸塩を含む水溶液を、貯蔵タンク1からポンプ2で電極5,6を備える容器3に流入し、電極間に交流電源装置4から電流を流し、二酸化ハロゲン塩を二酸化ハロゲンに変換し、二酸化ハロゲンを含む水溶液をノズル7から流出させる製造方法。前記供給水溶液が二酸化ハロゲン塩を、少なくとも1ppmの濃度で含み、製造された水溶液が二酸化ハロゲンを、0.5~5,000ppm、好ましくは1~500ppmの濃度で含む。水蒸気発生により圧力を上げる為に容器内に2又は3つの電極を設け、100~230Vの単相又は三相の交流電流を供給し、二酸化ハロゲン含有水溶液を生成させる。【選択図】図1
