为了明确5种室内植物对香烟烟雾PM2.5的净化效果,用封闭试验舱和实时粉尘检测仪对豆瓣绿、 花叶冷水花、 吉祥草、 吊兰、 常山5种植物在封闭环境中的净化效果进行测定.结果表明:在封闭的环境中5种植物均对香烟烟雾PM2.5具有净化作用,5种植物单位叶面积对香烟烟雾PM2.5的净化量从高到低分别是花叶冷水花>常山>豆瓣绿>吉祥草>吊兰;单位叶面积花叶冷水花在10 h内对香烟烟雾PM2.5的净化量达7.221 mg·cm-2,而吊兰的只有0.009 mg·cm-2;单株植株以花叶冷水花的净化量最大,吊兰的最小.植物净化香烟烟雾PM2.5的总量与植株数量不呈线性关系.在封闭的高浓度香烟烟雾PM2.5环境中放置10 h,5种植物均未出现...

In order to determine the effects of plants on PM2.5 adsorption,five indoor plants（ Peperomia tetraphylla,Pilea cadierei, Reineckia carnea, Chlorophytum comosum and Dichroa febrifuga） were measured in a closed environment by real-time dust detector. The results showed that the five indoor plants had the effect of adsorbing PM2.5,and the high concentration of PM2.5 in air could be reduced more than 90 percent after 10 h. The adsorption rate of PM2.5 of five plants per unit leaf area from high to low were： P. cadierei, D. febrifuga, P. tetraph...
