摘　　要：针对绝缘行业工作环境中甲苯等溶剂污染现象,选取金边吊兰和常青藤两种植物对4种浓度的甲苯进行降解,并采用气相色谱法检测甲苯的含量。结果表明:两种植物对4种浓度的甲苯都具有一定的降解能力,降解能力随甲苯浓度增加而降低;在降解时间相同的条件下,两种植物对低浓度(20mg/m3)甲苯的降解率比高浓度(160mg/m3)甲苯的降解率大,16h后金边吊兰和常青藤对20mg/m3甲苯的降解率分别达到45.6%和49.3%,对160mg/m3甲苯的降解率只有28.4%和21.6%。Chlorophytum Phnom Penh and ivy were used to degrade various concentration of toluene and then the toluene content was detected by gas chromatography. The experiments show that the two plant species can degrade the toluene to some extent and the degradation capability will de- crease with increasing the toluene content. Within the same period, the degradation rate of lower concentration（20 mg/m^3） of toluene is higher than that of higher concentration（160 mg/m^3）. After 16 hours of reaction with chlorophytum Phnom Penh or ivy, the degradation rates of toluene（20 mg/ m^3） are 45.6% and 49.3%, respectively; however, the same values for toluene（160mg/ m^3） are only 28.4% and 21.6%, respectively.
