光净化材料的应用研究

主要通过甲醛和苯被光净化材料分解的测定,阐述光净化材料的选择、光源波长、光源功率、光源距离等因素对净化效果的影响,同时还给出实际模拟装置试验的测定结果。认为不同光净化材料分解有害物质的效果不同,选择分解性能好的光净化材料合理制造装置,可以有效地加快细菌和有机污染物的分解。

Applied Research of the Photo-catalytic Degradation Materials for Air Cleaning

The effects of various factors,i.e.the selection of the photo-catalytic degradation materials for air cleaning,the wave length of the light source,the power of the light source and the distance between the light source and the photo-catalytic degradation material,on the effectiveness of air cleaning are discussed in this article based on the test results about the photo-catalytic degradation of formaldehyde and toluene,It is concluded that the effectiveness of the photo-catalytic degradation of the harmful substances in the air is dependent on the type of the photo-catalytic degradation material used.Therefore,using a well-chose material with sound photo-catalytic degradation performance to make useful photo-catalytic degradation devices for air cleaning would result in faster photo-catalytic degradation of the bacteria and the organic pollutants in the air.
