摘　　要：为了寻求治理室内挥发性有机污染物的措施,以豆瓣绿、鹅掌柴、富贵竹和袖珍椰子等4种常见室内植物为供试材料,采用五氟苯肼/气相色谱/质谱法(PFPH/GC/MSD)分析方法和动态熏气法开展了相关植物去除4种羰基化合物(乙醛、丙酮、丙醛和丁醛)的实验研究。结果表明,在有光照(3 000 lx)下,豆瓣绿、鹅掌柴、富贵竹和袖珍椰子4种植物对污染物的去除速率(μmol/(m2·h))范围分别为:0.24(丁醛)~1.36(丙酮)、0.25(丁醛)~0.69(乙醛)、0.07(丁醛)~0.30(乙醛)及0.57(丙醛)~0.75(乙醛),而在无光照下,相应的植物去除速率(μmol/(m2·h))分别为:0.07(丁醛)~0.27(丙酮)、0.09(丁醛)~0.29(乙醛)、0.02(丁醛)~0.22(乙醛)、0.13(乙醛)~0.45(丙酮),通过对比可以看出4种植物对C2~C4羰基化合物在光照下的去除效果明显优于在无光照的情况下。此外,4种供试植物对4种羰基化合物总的去除速率由大到小依次为:豆瓣绿(169.26μg/(m2·h))>袖珍椰子(149.23μg/(m2·h))>鹅掌柴(94.44μg/(m2·h))>富贵竹(29.85μg/(m2·h))。To seek measures against indoor air pollution of volatile organic compounds( VOCs),four common house plants including Peperomia tetraphylla,Schefflera octophylla,Dracaena sanderiana and Chamaedorea elegans were used as test materials for experimental studies on plant removal of low molecular weight gaseous carbonyl compounds( acetaldehyde,acetone,propionaldehyde,n-butyraldehyde) with analytic methods involving PFPH / GC / MSD and dynamic chamber. The results showed that the removal rates of the four species( Peperomia tetraphylla,Schefflera octophylla,Dracaena sanderiana and Chamaedorea elegans) under the illumination of 3 000 lx were 0. 24( butyraldehyde) ~ 1. 36( acetone),0. 25( butyraldehyde) ~ 0. 69( acetaldehyde),0. 07( butyraldehyde) ~ 0. 30( acetaldehyde),and 0. 57( propionaldehyde) ~ 0. 75( acetaldehyde) μmol m- 2h- 1,respectively,while under the dark condition,were 0. 07( butyraldehyde) ~ 0. 27( acetone),0. 09( butyraldehyde) ~ 0. 29( acetaldehyde),0. 02( butyraldehyde) ~ 0. 22( acetaldehyde),and 0. 13( acetaldehyde) ~ 0. 45( acetone)μmol /( m2·h),suggesting that the removal efficiency under the illumination was superior to that under the dark condition. The total removal rates of the four carbonyls decreased in the following order: Peperomia tetraphylla( 169. 26 μg /( m2·h)) > Chamaedorea elegans( 149. 23 μg /( m2·h)) > Schefflera octophylla( 94. 44 μg /( m2·h)) > Dracaena sanderiana( 29. 85 μg /( m2·h)).
