New house after the renovation of formaldehyde content is high, usually have to wait for some time before check-in. In order to accelerate the elimination of formaldehyde pollution, a lot of people hope legends adsorption capacity of charcoal.
The so-called charcoal adsorption capacity, primarily because this amorphous carbon has a lot of size in microns microporous structure calculations. Like water infiltration as in the sand. These channels can be infiltrated formaldehyde charcoal inside. However, in addition to formaldehyde housed in tunnels, the charcoal and no special mechanism to limit their freedom, as the evaporation of water from the sand and clean inside as formaldehyde may be volatile from charcoal inside.
Make charcoal adsorption of formaldehyde experiment researchers noted, activated carbon adsorption of formaldehyde is not stable, not even as with the water molecules get closer. If the indoor air humidity, water molecules adsorbed will be more than the formaldehyde, possibly even before the formaldehyde adsorption on charcoal to squeeze down. If you can add some substance to react with formaldehyde in the pores in the charcoal, so as to realize the elimination of formaldehyde, the effect will be better. But there is no such product.
In actual use, changing environmental conditions, charcoal adsorption of formaldehyde there is no way to determine, indoor formaldehyde content is not reduced also unknown.
In addition to bamboo, with green formaldehyde treatment effect is not very good. Formaldehyde is harmful to the plant, the reaction of formaldehyde gas sensitive plants such as Bougainvillea at high formaldehyde concentration in the environment will be injured or even killed. This is because the combination of formaldehyde and plant cell superoxide dismutase, these key proteins lose activity, and further damage the cell membrane structure.
Some plants of formaldehyde endurance is stronger, even detoxification function. Many of these plants are to be regarded as a decontamination God grass. But the reality is, there are some for removing formaldehyde in the "pipeline" of these plants, they will formaldehyde with a specific chemical reaction to produce the amino acid (serine), or directly into carbonic acid and carbon dioxide to enter the substance cycle, for the manufacture of new sugar, fat or protein.
Note, however, that this is only a defensive response in plants. The researchers simulated room containing formaldehyde, measured some common indoor ornamental potted plants to formaldehyde processing power. Absorption efficiency obtained from the experimental point of view, the ability to handle formaldehyde plant in a short time is not enough to significantly reduce the concentration of formaldehyde in general the living room.
For example, the efficiency of the more popular spider plant is one square meters per hour blade 0.15 mg formaldehyde. Typically a spider plant leaf area less than 0.1 square meters. That is to say, the total amount of formaldehyde, a spider plant within one day can handle only 0.36 mg. If 100 square meters, 3 meters within storey room, the formaldehyde concentration of 0.5 mg / cubic meter, a total of 150 mg of formaldehyde, to be reduced to the safety standards (0.1 mg / m3) would need to be cleared at least 120 mg of formaldehyde. That tree spider plants to hard work 333 days. Of course, this does not count in the new decorative materials from out of the volatile formaldehyde.
Charcoal, green plants are not good enough (of course, they have nothing affected area), what method is most effective? Experiments show that the ventilation window is the easiest and most effective means to remove formaldehyde.
