摘要：

城市住宅的室内空气污染十分严重，甲醛已经成为中国目前室内空气中的首要污染物。本实验以绿萝、常春藤与活性炭为研究对象，采用密闭箱法进行了净化甲醛能力的研究。实验结果表明，绿萝、常春藤与活性炭均对室内甲醛有良好的净化作用，24 h后的甲醛净化能力大小依次为：常春藤＋活性炭（甲醛去除率38.27%）＞常春藤（34.31%）＞绿萝＋活性炭（32.20%）＞绿萝（5.61%）＞活性炭（3.73%）；10天后的净化效果排序为：常春藤＋活性炭（69.91%）＞绿萝＋活性炭（64.28%）＞常春藤（60.44%）＞活性炭（57.50%）＞绿萝（24.99%）。植物与活性炭联合作用对甲醛净化效果比单一用植物或活性炭效果好，而且长期作用比短期作用效果好。

Abstract:

The indoor air pollution in urban resident is very serious, formaldehyde has become one of the most important indoor air pollutants in China. In this study, ivy (Scinda Psusaureu), green dill (Hedera nepalensis van. Sinensis) and activated carbon are selected as the research objects, and we use the closed chamber technique to study the absorption capacity of plants and chemicals on formaldehyde. The results show that green dill, ivy and activated carbon are all good for indoor formaldehyde purification. One day later, the purifying efficiency decreased in the order as follows: ivy + activated carbon（formaldehyde cleaning rate is 38.27%）> ivy (34.31%) > green dill + activated carbon (32.20%) > green dill (5.61%) > activated carbon (3.73%). Ten days later, the purifying efficiency decreased in the order as follows: ivy + activated carbon (69.91%) > green dill+ activated carbon (64.28%) > ivy (60.44%) > activated carbon (57.50%)> green dill (24.99%). Combining the plants and activated carbon have the better efficiency of formaldehyde cleaning rate than using plants or activated carbon singly, and long time have better effect than short time.
