1, plant removal method
Green plants produce photosynthesis under the action of sunlight, which can absorb carbon dioxide in the air, produce oxygen and play a role in refreshing the air. But it is misunderstood that plants can absorb formaldehyde. But the fact is that formaldehyde will react with protein, nucleic acids and lipids in plants, which is harmful to plant cells and even leads to plant death. In an environment full of formaldehyde, it is difficult for plants to protect themselves, let alone serve people.
2. Activated carbon removal method
In recent years, the activity of activated carbon is still relatively high, and merchants claim that activated carbon has a strong ability to absorb formaldehyde. There are many tiny pores on activated carbon, which can completely let formaldehyde pass through unimpeded. One weakness of activated carbon is that it is easy to adsorb and saturate, and it is difficult to reuse it in the later stage. Because the absorbed formaldehyde cannot be completely volatilized under the scorching sun exposure, it is also difficult to reuse. The absorption capacity of activated carbon to formaldehyde is very limited, but it undoubtedly plays a certain role, but it has little effect.
3, the removal method of mature vinegar
This method should be regarded as a folk gathering. Bian Xiao explained the principle that the main functional component of aged vinegar (white vinegar) is acetic acid, which is an important derivative of oxygenated hydrocarbons. But acetic acid does not react with formaldehyde. Because vinegar itself has a volatile pungent sour taste, which can mask the smell of formaldehyde, people mistakenly think that vinegar removes formaldehyde. In fact, formaldehyde has not decreased, and it still exists in the indoor environment, but its taste has not attracted our attention.
4, grapefruit peel, pineapple peel removal method
Pomelo peel and pineapple peel have peculiar fruity fragrance, rich taste and lasting fragrance. Actually, according to folk rumors, in addition to formaldehyde's principle is the same as vinegar. Pomelo peel and pineapple peel can't remove formaldehyde by themselves, but cover up the smell of formaldehyde with their own taste. Although grapefruit peel can't be in addition to formaldehyde, it can freshen the air and prevent mosquitoes, so putting a grapefruit peel at home is very helpful to adjust the air.
5. Chemicals outside in addition to formaldehyde
Most formaldehyde scavengers on the market are synthesized by chemical components. Some inferior products cost only a few dollars, but the price can be sold for more than ten times. At present, the country has not issued a clear standard of formaldehyde scavenger, so the products on the market are mixed. Even if it reacts with formaldehyde, it can not guarantee the subsequent safety and hygiene, but it is likely to cause secondary pollution.
So, what about in addition to formaldehyde?
In fact, in addition to formaldehyde's method is very simple. Most indoor formaldehyde can be discharged after opening the window for more than six months. If you want to speed up this process, you can use Maya blue, photocatalyst and other materials to remove formaldehyde more thoroughly. In short, the most important and simplest way is to open more windows for ventilation, maintain good living habits and reduce the harm of formaldehyde to the body.
