B-37 Development of Air Cleaning and Sterilization System with Oblique Honeycomb by Using Chlorine Dioxide : Sterilization and Deodorization Properties of Chlorine Dioxide

Abstract

Recently, it becomes more important to reduce airborne microbes and nasty smell from the viewpoint of indoor air quality. We developed an air cleaning and sterilization system with oblique honeycomb by using chlorine dioxide (ClO_2). In this study, we examined the sterilization and deodorization properties of chlorine dioxide. Gaseous chlorine dioxide showed the ability of sterilization for the microbes at the concentration of 0.1ppm, and decomposed some compounds, such as trimethylamine, ammonia and methylmercaptan. It was considered that chlorine dioxide was suitable for the cleaning and sterilization system.
