Abstract: PURPOSE: A method for preparing chlorine dioxide in high yield is accomplished by proper adjustment of the supply ratio of sodium chlorite and chlorine, by which hydrogen-ion concentration condition is optimized. The chlorine dioxide, when applied to cooling water, showed excellent bactericidal effect against Legionella pneumophila when applied to cooling water. In addition, chlorine dioxide has proven to be effective in eliminating alien algae in cultivating lava. CONSTITUTION: In the generation of chlorine dioxide using sodium chlorite and chlorine, by using a flowmeter and a chemical pump, Cl2 supply rate and NaClO2 supply rate are controlled to adjust pH in the range 1.9 to 2.0. For the smooth dissolving of chlorine gas into sodium chlorite solution, chlorine gas is supplied through glass wool(7), and a baffle(8) is installed to be perpendicular to a sodium chlorite/chlorine inlet. The baffle plays role in converting laminar flow to turbulent flow within short time.
