Fine dust is air pollution caused by fine particulate matters, categorized as fine dust less than 10 μm(PM 10) in diameter, and ultrafine dust less than 2.5 μm(PM 2.5) diameter. According to '미세먼지 종합 관리대책', domestic fine dust are emitted by direct emission about 30%, while about 70% is indirectly emitted by reacted with NOx, SOx and VOCs in the atmosphere. In order to reduce such a fine dust and precursor, evaluation tests of photocatalyst raw material or related manufacturers have been rapidly increased.ISO standard offers several test methods for evaluating the performance of photocatalysts. But this standard does not apply to powder photocatalytic materials, and then, it is necessary to study a test method to evaluate them. In addition, there is no standard for SO2 removal performance test, which is a fine dust precursor. In this study, the test method of powder photocatalytic materials and SO2 removal performance test were conducted based on ISO test standard. |
