摘要
甲醛是室内空气的主要污染物之一,该试验模拟居室装修后的甲醛污染环境,对9种常见观赏植物进行甲醛熏气处理,测定植物吸收甲醛的能力。试验将植物盆土与茎叶部分隔开,放入自行研制的甲醛熏蒸箱中,测得熏蒸后植物单位叶面积吸收甲醛的量作为指标评价了不同植物对甲醛气体的净化能力,结果显示:所选植物中杏叶梅吸收甲醛的能力最强,而鸟巢蕨吸收甲醛的能力较弱。
Formaldehyde is one of the main pollutants in indoor air.The test is about the formaldehyde fumigation treatment on 9 kinds of common ornamental plants by simulating the indoor formaldehyde pollution after renovation.The study separated the plant from the soil ,and put the plant in the formaldehyde fumigation box, then evaluated the purification ability of different plants on formaldehyde by measuring the amount of per unit leaf area＇ s absorption of formaldehyde after the fumigation.The results showed that the Kcdanchoe synsepala had the strongest ability to absorb formaldehyde among the plants while the Neottopteris antiqua had the weakest ability.
