天南星科植物对甲醛净化效果的研究

Studies on Purification Effect of Araceae Plants on Formaldehyde

在室内,甲醛作为一种有害气体给人们身心健康带来很大影响,室内植物既可供观赏,又可以吸收甲醛等有害气体。采用玻璃环境测试舱模拟甲醛污染环境,研究天南星科的16种(品种)植物对甲醛的净化效果。实验结果表明:天南星科植物对甲醛均有一定吸收能力,但净化能力差异较大,这为室内污染环境选择植物提供了理论指导。此外还讨论现在研究中存在的问题,并对未来研究的发展进行展望,以期为植物净化空气的应用提供科学依据。

Formaldehyde as a kind of hazardous gas has significant impacts on physical and mental health of people.Indoor plants are not only available for viewing,but also can absorb formaldehyde and other harmful gases.A glass environmental test chamber was used to simulate formaldehyde polluted environment so as to study formaldehyde purification effect of 16 Araceae pants.Experimental results show that the Araceae plants have certain capacity of absorbing formaldehyde,but the purification abilities are significantly different.It provides rational theoretical guidance for plants selection.Besides,this paper also discuses the problems existing in current researches and looks into the future research development,in the hope of providing scientific basis for air purification by plants.
