摘要
装修材料和家具释放的有害气体严重污染了室内的生活环境,其中甲醛对人体的危害尤为突出。为了控制和减少室内空气污染对人体健康的危害,确保室内空气环境的安全。以新装修的居民住宅为研究对象,采用酚试剂分光光度法对室内甲醛质量浓度检测分析,探究了植物、温度、通风时间和房间类型对室内甲醛质量浓度的净化作用。结果表明:温度与装修材料中的甲醛挥发速率呈显著正相关(P<0.01),而室内甲醛质量浓度与室内通风时间呈显著负相关(P<0.05)。卧室中甲醛的含量显著高于其他房间的含量;绿萝、芦荟、常春藤、龙舌兰、吊兰对甲醛的去除率分别为78.6%、65.7%、60.0%、45.7%、42.9%。升高温度和延长室内通风时间有利于甲醛的挥发去除;绿色盆栽植物对甲醛的吸收能力为:绿萝>芦荟>常春藤>龙舌兰>吊兰。
The harmful gases released from decoration materials and furniture heavily pollute the indoor living environment, especially formaldehyde which severely endangers human health. In order to control and reduce the harm of indoor air pollution to human health, and ensure the safety of indoor air environment, spectrophotometry is employed to detect and analyze the quality and concentration of formaldehyde in a newly decorated residential for the exploration of purification about plant, temperature, ventilation time and room type on indoor formaldehyde concentration. The results indicate that there is a significant positive correlation between temperature and formaldehyde volatilization rate in decoration materials(P<0.01), while a significant negative correlation between indoor formaldehyde concentration and ventilation time(P<0.05). The level of formaldehyde in the bedroom is significantly higher than that in other rooms. The removal rate of formaldehyde by Scindapsus aureus(Linden et Andre) Bunting, Aloe vera L. var. Chinensis(Haw.) Berg, Hedera nepalensis K, Koch var.sinensis(Tobl.) Rehd, Agave americana L and Chlorophytum comosum(Thunb.) Baker are 78.6%, 65.7%, 60.0%, 45.7% and 42.9% respectively. Rising temperature and prolonging ventilation time are beneficial to volatilization of formaldehyde. The absorption ability of green potted plants to formaldehyde is as follows: Scindapsus aureus(Linden et Andre) Bunting>Aloe vera L. var. Chinensis(Haw.) Berg>Hedera nepalensis K,Koch var.sinensis(Tobl.) Rehd>Agave americana L>Chlorophytum comosum(Thunb.) Baker.
