Abstract: PURPOSE: A removing method for noxious tide using chlorine dioxide is provided, which can remove noxious tide effectively without secondary pollution by spreading chlorine dioxide solution on a sea area with red tide or green tide. CONSTITUTION: The chlorine dioxide is produced by reacting sodium chlorite with chlorine; 2NaClO2 + Cl2 → 2ClO2 + 2NaCl, which exists as a yellow-green gas at normal temperature, is used in an aqueous solution by dissolving in water to make the concentration at a ratio of 0.1-1ppm, and removes noxious tide with microorganisms(such as Cochlodinium, Chaetoceros, Mesodinium, Gymnodinium, and Gyrodinium) as well as toxic substances produced by them due to strong oxidizing power thereof. But a halogenide is not produced as a by-product, and the chlorine dioxide is easily resolved into oxygen molecule and chlorine ion by sunlight.
