摘要

為提升室內空氣品質，降低室內生活環境危害風險，以維護國民健康，我國制定「室內空氣品質管理法」，且將於今（2012）年11月23日正式實施。本研究擬透過常見室內觀葉植栽搭配不同光源對淨化室內空氣進行量化實驗，提出應用策略。實驗選用臺灣室內常用之觀葉植栽：白鶴花、黃金葛、白肋等；搭配T8、T5與鹵素燈等三種光源頻譜，以「足尺實驗」及「小尺寸環控箱實驗」進行一定濃度之甲醛吸附試驗，評估其於不同境界條件下之甲醛吸附、脫附等現象。結果發現：1.各種植栽搭配不同光源於環控箱內，在無換氣條件下吸附甲醛濃度皆出現「短暫效果」。2.各種類植栽於小尺寸環控箱內，實驗開始約100〜200分鐘左右，甲醛濃度衰減至最低點，爾後便開始出現脫附現象。建議密閉式空間應用植栽淨化室內空氣時，應注意植栽差異的吸脫附時間，以避免植栽脫附有害化學物質回溯於室內空氣中。3.「白鶴花」搭配T8日光燈、黃金葛搭配T8日光燈、「白肋」搭配鹵素燈及T8日光燈、對甲醛吸附具明顯效果。

For enhancing the quality of indoor air condition and lowering the risk of indoor living environment to safeguard public health, our government publish the Low of Indoor Air Quality Risk Management which will be implemented on 2012/11/23.This research provides the application strategy through quantitative experiments of how indoor foliage plants can clean indoor air quality under different spectra. This research chooses general indoor foliage plants in Taiwan, like Chinese Alias, Pothos Vine, Hetaeria Cristata, and use 3 different spectra: T8, T5 & halogen lamps for the absorption test of formaldehyde with fixed concentration (by full-scale small-scale chambers),to evaluate the phenomenon of absorption/desorption on formaldehyde under different boundary condition.According to the research result:1. In the experiment of small-scale chamber, it was found that under different artificial illuminants, the plants had a temporary effect on formaldehyde absorption. That is, in the airtight space, the plants were still capable of temporary absorption, but the effect would vanish as time passed.2. Plants in chamber, the concentration of formaldehyde is lowest when 100 ~ 150 minutes passed. Then the concentration to rise again as same as beginning. Therefore, the key point is understand the key timing of ones, take it out for desorption, while people employ indoor foliage plant to purify the chemical pollutants, especially closed room.3. It was found that Chinese Alias significantly absorbed formaldehyde under T8. , Pothos Vine significantly absorbed formaldehyde under T8, and Hetaeria Cristata significantly absorbed formaldehyde under T8 and halogen lamps.
