空気質の改善・浄化への竹炭の応用技術

抄録

The use of bamboo charcoal, which is one of the carbon from wood, attracts attention from the viewpoint of the environmental protection. Bamboo charcoal has high adsorption removal ability to various substances. In addition Bamboo charcoal is effective also for the filtration of the suspended solid and the bacterium by the macro pore that originates in the plant frame structure. In present paper, a new concept of gas clean technology by bamboo charcoal and TiO₂ with UV light irradiation was proposed. Its system is composed of TiO₂-coated bamboo charcoal, TiO₂-coated silica gel and UV lamp. Water vapor is adsorbed by bamboo charcoal and fine particles and airborne bacterium are trapped on the surface of it. Trapped contaminant is degraded by TiO₂ and UV light. In addition, the degradation is promoted by •OH produced by adsorbed water vapor. The air purification sanitization possibility in high efficiency for this system was clarified.
