Abstract
This study shows an air-purification test by the UV lamp on which TiO2 catalyst is deposited with glassfiber in the reactor chamber. This test was based on the fundamental data of air-purifier as assessing aremoving ability on various contaminants such as CH3COOH, NH3, NO and SO2 as variation of the TiO2coating, the wave of UV lamp, and the additive CaO. As a result, the highest decomposing removal ratio wasshown when 5-times coated glass fiber was used. It can be due to the recombination reaction of electrons andelectron-hole in the loaded CaO. Thus, the decomposing removal ratio increased as the recombination ratiodecreased. In addition, it was confirmed that the decomposing removal ratio lowered when CaO wasconsiderably deposited because it hided the lamp of OH-1 radical.
