Abstract

This study was performed to determine the optimum conditions for the production of gaseous chlorine dioxide (ClO₂) from aqueous ClO₂ (HCl+NaClO₂). When 1 N HCl was reacted with various concentrations of NaClO₂ (50,000-500,000 mg/mL), the highest concentration (695 mg/L) of gaseous ClO₂ was obtained from the aqueous ClO₂ containing 100,000 µg/mL NaClO₂. Next, the effects of relative humidity (RH; 43, 85, and 100%) and temperature (4, 12, and 25ºC) on the production of gaseous ClO₂ were investigated. It was observed that the concentration of gaseous ClO₂ was increased as RH was decreased, or the temperature was increased. Finally, it was confirmed that the amount of gaseous ClO₂ was highly correlated (R²=0.9546-0.9992) with the volume of aqueous ClO₂. The results of this study provide useful information for designing a sanitization program using gaseous ClO₂ under various environmental conditions.
