Ask ha, can onions remove formaldehyde?

Myth 1: Onions and grapefruit peels can remove formaldehyde.

Many people say that onions and grapefruit peels can remove formaldehyde because they can release the smell of incense and cover up the smell of pollutants at home, but in fact, it is not that the pollutants are gone, but they can't smell the smell. Therefore, onions, grapefruit peels, etc. not only cannot remove formaldehyde, but make us mistakenly think that formaldehyde is gone and move in with confidence, increasing the probability of formaldehyde poisoning.

Myth 2: Tea can remove formaldehyde.

Most people think that tea can remove formaldehyde, which is wrong. The pores of tea and the diameter of formaldehyde are much larger, and formaldehyde enters from this end and comes out from the other end, so no amount of tea can remove formaldehyde.

Myth 3: Lighting a candle can remove formaldehyde.

When the candle is burned, it can convert formaldehyde in the air into formic acid, so as to achieve the effect of removing formaldehyde. However, when the candle is burned, it will consume a lot of oxygen, and it will also generate carbon black, carbon monoxide and other toxic substances, so it is not advisable to light a candle to remove formaldehyde.

Here are the effective ways that experts recommend to remove formaldehyde:

Method 1: Enhanced ventilation.

The easiest way to remove formaldehyde is to open the window for ventilation, as long as effective ventilation is carried out, indoor formaldehyde and other pollution will be immediately reduced, but this is only temporary, once the window is closed, formaldehyde will be released again. In addition, when the wind speed is small, the window is opened, and there is no effect on formaldehyde. Therefore, while opening windows for ventilation, it should be combined with other methods to remove formaldehyde.

Method 2: Activated carbon.

Activated carbon is a relatively primitive formaldehyde removal material, which is cheap and has strong adsorption, and will have a good formaldehyde removal effect when used in large quantities. However, it can only adsorb formaldehyde, cannot decompose formaldehyde, and is also easy to saturate. Therefore, experts recommend replacing it once every 15-20 days to avoid affecting health after formaldehyde saturation.

Method 3: Lotting Stone.

Lotting stone is a new type of formaldehyde removal material, composed of black and white particles, which has a good effect on the control of indoor formaldehyde and other air pollution. Moreover, in addition to the efficient adsorption of formaldehyde, Lotin stone can also decompose formaldehyde into harmless substances and release them into the air. Therefore, the Lotting stone is not saturated.

In addition, it is valid for up to 3 years.

Method 4: Plants.

At present, plants such as pothos, spider plant, chrysanthemum, and tiger tail orchid on the market can not only beautify the environment, but also remove formaldehyde, killing two birds with one stone. However, the plant's ability to purify formaldehyde is also limited, and once it exceeds its own metabolic capacity, the plant will also "strike".

Onions actually can't remove formaldehyde, you will feel that the taste is gone because the smell of onions covers the taste of formaldehyde, and onion formaldehyde removal is actually a palliative way to cure the root cause. There are three ways to really work:

1. Ventilation: release the odor as soon as possible. If the car smells, you can park the car in the sun, bask in the sun to raise the temperature, speed up the release of odors, and then open the window to ventilate the formaldehyde to release it. It can be eliminated in about half a year.

2. Rely on formaldehyde removal materials: This is basically a physical adsorption method, such as activated carbon, but it needs to be changed once every two weeks. There are also materials with physical adsorption and chemical decomposition, such as Yeguang mud materials, which have a larger adsorption capacity than activated carbon and can be used for a long time.

You can stay in it for a long time for about 1 month.

3. Seal the source of pollution and prevent formaldehyde from being released: use some chemical reagents to smear on the seat leather to form a closed film, formaldehyde will not come out, and there is a disadvantage that it is easy to damage the leather and cause chemical pollution.

No, you can only use the smell to cover the formaldehyde smell. Formaldehyde is only more ventilated, and activated carbon can be adsorbed.

No formaldehyde was removed at all. Put in the water and peel the onion in the corner of the room.

Onions can also remove formaldehyde, and the way to remove formaldehyde from onions is to spread Mr. Yang Cheng throughout the house and wait for the onion to be absorbed, or put it in some corner places, which is okay.

Onions can remove formaldehyde, and the way to remove formaldehyde is to cut the onion into small slices, then soak it in water and place it in every corner of the room.

There is no effect on removing formaldehyde at all. You can put it in water, you can peel off the onion and put it in any corner of the room.

Can onions remove formaldehyde? Formaldehyde is a chemical product that can simply be treated with natural plants – tea, onions, etc. Although indoor ventilation can improve indoor air to a certain extent, it cannot be expected that it can completely eliminate indoor pollution.

Indoor harmful gases exceed the standard, and ventilation cannot help.

1. Onions that are often used to remove decoration odorsOrange peeland grapefruit peel are based on the principle that its molecule is larger than the formaldehyde moleculeSo it can mask the "odor" but it's not really adsorbed. Pineapple just reduces the smell of formaldehyde, which is still volatile.

Target. In addition to formaldehyde, pineapple smells and reacts with formaldehyde, which may cause other harm to the human body. The same goes for onions and tea."

A way to remove formaldehyde from onionsPut the pot in the corner of the room, the smell will soon be gone, put more plants. Ventilation should be used for a few hours in the morning and evening.

2. In addition, when using formaldehyde scavengers, it is necessary to choose air that will not produce secondary pollutionPurifiersFor example, the effect of Truesense is not bad, not only can quickly remove harmful gases such as formaldehyde, but also quickly remove odors. Activated carbon.

Formaldehyde treatment is adsorption, but it cannot "lock" formaldehyde release. It is recommended to expose the activated carbon outdoors for an hour or two after half a day indoors to allow the adsorbed formaldehyde to volatilize, and then use it repeatedly. Removing formaldehyde from activated carbon is a slow process.

Maybe it would be better for a little longer. The effect of the plant is similar to that of activated charcoal, and the plant is spider plant.

The effect is most obvious. However, after being left for a period of time, the spider plant that has absorbed too much formaldehyde will turn yellow, thus losing the effect of readsorption.

3. The air purifier uses chemical methods. The purifier is excited by an electric arcNegative ionsIt produces bromine oxide, a strong oxidizing agent, which oxidizes formaldehyde and other substances in the air, and finally decomposes into carbon dioxide.

and water. Since furniture and the like constantly release formaldehyde, it is best to keep the purifier working in order to ensure safety and use effect. The filter inside the purifier has a lifespan and should be replaced regularly.

1. The onion can not remove formaldehyde, because it does not contain substances that can adsorb formaldehyde, and the reason why the smell of formaldehyde cannot be smelled after placing the onion indoors is entirely because the smell of the onion covers up the smell of formaldehyde.

2. Commonly used methods to remove formaldehyde:

1) Ventilation method.

Ventilation formaldehyde removal method is the most commonly used method, this formaldehyde removal method mainly uses the movement of air convection to bring harmful gases to the outdoors, this formaldehyde removal method is both economical and efficient.

2) Placement plant removal method.

Plants have a strong absorption capacity, can effectively absorb indoor formaldehyde, such as cactus, spider plant, reed, ivy, iron tree and other plants have good adsorption capacity, among which large leaf surface and vanilla plants will absorb formaldehyde effect will be better.

3) Physical adsorption method.

In addition to formaldehyde, physical adsorption can also be used, for example, activated carbon has a certain adsorption effect, and some can be placed indoors to remove formaldehyde, but it can only play an adsorption role, and has a certain saturation, so it needs to be exposed to the sun after a certain date, and then reused.

4) Formaldehyde scavenger removal method.

Formaldehyde scavengers are the most direct and effective way to remove formaldehyde, but this is also very demanding for products, such as chemical products, nano photocatalysts and plant stock solutions, but such products may cause secondary pollution, so they must be used with caution.

Of course, formaldehyde can't be removed, but the smell of onions fills the air, giving people an illusion. What do you use to remove formaldehyde from onions? Is it spicy?

Formaldehyde removal is first of all source control, using less formaldehyde-containing materials, then ensuring ventilation, and the third is absorption.

Onions do not have any ability to break down formaldehyde.
