某型空气净化器除毒效果检测

目的探讨某型号空气净化器除毒效果。方法在一定面积的房间中，模拟产生一定浓度的10种有害毒物，让其平衡后分别测定不同时间各种毒物的自然衰减率、开机衰减率．计算空气净化器在不同时间的除毒效果。结果空气净化器开机60min后，对可吸入颗粒物、甲醛、一氧化碳、氮氧化物、苯、丙酮、异丙醇、三氯乙烯、甲苯、总烃的除毒效率分别为18．7％、13．5％、16．7％、14．8％、52．5％、56．8％、60．1％、46.3％、40．0％、58．9％。开机160min后，对上述物质的除毒效率分别为31．7％、38．3％、31．1％、22．8％、62．4％、70．0％、78．8％、59．3％、50．1％、57．9％。结论某型号空气净化器对有机物的吸附能力较大，对无机物的吸附能力较少，对有机蒸气的除毒效果较好。

Research on the Decontamination Effect of an Air Purifier

Objective To explore the decontamination effect of an air purifier. Methods Formaldehyde,benzene, toluene, carbon monoxide, nitrogen dioxide, inhalant particulates, acetone and isopropyl alcohol were detected and the rates of decontamination were evaluated from different time when the air purifier was operated. Results After the air purifier has worked for 60 minutes, the decontamination rates of different chemicals changed from 13.5% to 60.1%, and after 160 minutes, the decontamination rates changed from 31.7% to 78.8% in spots,Conclusion The decontamination effect of the air purifier was good for the organic chemicals and it has less adsorptive ability for inorganic dust.
