摘　　要：目的研究钠米光催化空气净化器的降解效率,为钠米光催化空气净化器的卫生学评价提供科学依据。方法在模拟实验室挥发有机物质创造污染源环境,开启空气净化器,然后采样进行测定。结果苯的降解效率为91.0%;甲醛的降解效率为78.8%;可吸入颗粒物为93.0%;杀菌率为83.0%。结论纳米光催化技术对室内空气污染物有一定的净化效果。Objective In order to know the removal effectiveness of photocatalytic air cleaner, so as to provide scientific basis for hygiene evaluation of photocatalytic air cleaner. Methods first, establish polluted environment by volatile organism in mimic laboratory, then, switched on the photocatalytic air cleaner and sampled and detected. Results The removal effectiveness of benzene, formaldehyde and inhalable particulate were 91.0%, 78.8% and 93.0%, respectively. The sterilization effectiveness was 83.0%. Conclusion The photocatalytic technology had certain removal effectiveness on indoor air pollutant, which offered a base of the removal effectiveness of indoor air pollutant by photocatalytic air cleaner.
