摘　　要：目的观察选取的两种空气净化剂对坑道内挥发性污染物氨气和硫化氢的净化效果。方法将植物空气净化剂及竹炭滤料分别放入密闭的容积为1 m3的小型环境舱内,用采样器往其中吹入有害气体,用风扇混匀后测定空间内有害气体的浓度,每0.5 h分别观察空气净化剂对几种挥发性污染物的净化率。结果 植物空气净化剂对氨气和硫化氢的两小时最大净化率分别为50%和37.5%,竹炭滤料净化剂对氨气和硫化氢的两小时最大净化率分别为60%和62.5%。结论选用的两种空气净化剂对坑道挥发性污染物氨气和硫化氢都有较好的净化效果,可以用于坑道内有害气体的消除。Objective To observe the purification effects of two different air purificants on the volatile pollutants（NH3 and H2S） in tunnels.Methods The plant air purificant and the bamboo charcoal were put into a 1 m3 box of airtight minitype environment,respectively.The harmful gases were insufflated into the box with sampling implement and mixed them.At an interval of half an hour,the concentration of harmful gases was mensurated to observe the purification rates of two air purificants.Results The maximal purification rates of the plant air purificant to NH3 and H2S in 2 h were 50% and 37.5%,respectively.The maximal purification rates of the bamboo charcoal air purificant to NH3 and H2S in 2 h were 60% and 62.5%,respectively.Conclusion The purification effects of two air purificants are preferable to the volatile pollutants（NH3 and H2S） in tunnels.The air purificants can effectively eliminate the harmful gases in tunnels.
