植物吸附法
Plant adsorption method
研究发现甲醛吸收效果更好的是绿萝,吸收效果更差的君子兰。对甲醛抗性较强的绿萝、金边虎尾兰和吊兰,均可以用来做吸收甲醛的植物。虽然,植物吸附法能够去除一定甲醛,但是吸附缓慢,装修材料释放甲醛的量远远大与植物吸附的量,植物吸附法在净化室内甲醛时效果并不显著。
The results showed that the best formaldehyde absorption effect was found in mallow, and the worst in Clivia. The plants with strong resistance to formaldehyde, such as Mallory, Cymbidium and Chlorophytum, can be used to absorb formaldehyde. Although the plant adsorption method can remove a certain amount of formaldehyde, but the adsorption is slow, the amount of formaldehyde released by decoration materials is far greater than that of plant adsorption, and the effect of plant adsorption method in purifying indoor formaldehyde is not significant.
活性炭吸附法
Activated carbon adsorption method
活性炭净化室内空气中甲醛的原理是依靠其自身发达的比表面积和孔隙结构,通过空气流通被动的吸附甲醛等污染物到活性炭的空隙中,因此,活性炭的孔径结构越发达、比表面越大该活性炭的吸附能力就越强。物理吸附法虽能去除甲醛但其对空气流动依赖较大,当室内空气不流动时,其只能吸附与其接触空气内的甲醛,对室内甲醛整体吸附效果并不显著。当其吸附饱和后,对甲醛的降解效果会大幅度降低,不能够持续有效的吸附室内甲醛。
The principle of purifying formaldehyde in indoor air by activated carbon depends on its developed specific surface area and pore structure, and passively adsorbs formaldehyde and other pollutants into the space of activated carbon through air circulation. Therefore, the more developed the pore structure and the larger the specific surface area, the stronger the adsorption capacity of activated carbon. Although the physical adsorption method can remove formaldehyde, it depends on the air flow. When the indoor air is not flowing, it can only adsorb the formaldehyde in the contact air, and the overall adsorption effect of indoor formaldehyde is not significant. When the adsorption is saturated, the degradation effect of formaldehyde will be greatly reduced, and it can not continuously and effectively adsorb indoor formaldehyde.
