13种常用室内观赏植物对甲醛净化效果

【研究目的】给人们生活提供有效的降低室内甲醛污染的方法；【方法】选用13种常用室内观赏植物，将盆土与茎叶部分隔开，放入自行研制的甲醛熏蒸箱中，对植物进行熏蒸实验，测得熏蒸前后甲醛的变化量和植物叶面积，以单位叶面积甲醛减少量来比较植物间吸纳甲醛能力的大小并排序。【结果与结论】结果显示，合果芋等吸纳甲醛的能力较强，而芦荟等吸纳甲醛的能力较弱。

The comparison of ability of adsorbing formaldehyde among 13 species of indoor ornamentals

ConclusionIn order to provide people for an effective method of removing indoor air pollution of formaldehyde;Method13 species of indoor ornamentals were chosen in this experiment. Pot and soil were covered by plastic film to separate from the top plants, before they were put in the self-designed glass boxes. After the given concentrated formaldehyde was vented into the glass boxes for 15h and 24h, the concentration of formaldehyde and plant leaf area were measured. Thus the adsorption ability of 13 plants were ordered by comparing the decreasing of formaldehyde amount per unit of leaf area(mg/m2);Results and ObjectiveThe results showed that the adsorption ability of Syngonium podophillum etc. is much stronger than that of Aloe vera var.chinensis etc.
