Do onions remove formaldehyde, can onions remove formaldehyde

Onions can't remove formaldehyde at all, it doesn't have this effect.

Excessive formaldehyde is very harmful to the human body, and long-term exposure to excessive formaldehyde will cause many diseases, such as leukemia. Onions cannot remove formaldehyde. The method of using onions to remove formaldehyde is wrong and futile.

In order to effectively remove aldehydes, it is necessary to use correct methods, such as window ventilation, activated carbon adsorption, photocatalyst purification, etc.

Onions can not eliminate the smell of formaldehyde, comprehensive some methods to remove formaldehyde, choose photophyll materials to decompose formaldehyde;

1. Use some photocatalysts and photophyll to remove formaldehyde materials, photocatalysts and the like can decompose formaldehyde when exposed to light, and the industry is used to remove formaldehyde more, and photophyll is a formaldehyde catalyst extracted from plants, which will be faster and safer, and is generally used more in family conditions.

2. Ventilation, after the treatment of key pollution sources, the next step is to ventilate more, so that the formaldehyde that decomposes in the early stage is released.

3. Activated carbon, place some adsorption activated carbon materials, and Yeguang mud materials can adsorb formaldehyde for a long time.

4. Photocatalyst, photocatalyst and the like can decompose formaldehyde when exposed to light.

5. Herbal formaldehyde purifying agent, plant liquid decomposition and removal method.

6. Air purifiers and fresh air systems are similar to the principle of ventilation, and these will generally be used when outdoor pollution is serious, but the effect is similar to the ventilation effect.

7. Wipe the furniture with salt water to remove the smell.

8. Plants, plants are mainly ivy, pothos, spider plant, aloe vera, tiger tail rot, cactus, which are used for a long time.

9. Grapefruit peel, aged vinegar, etc. to remove odors.

Yes. If the formaldehyde in the newly renovated house exceeds the standard, you can use onions to suck it up.

Peel the onion first, cut it into shreds, then put it on a plate, put it in drawers, cabinets, and all corners of the room (don't stuff the onion in the cabinet, open the cupboard), after a few days, you will find that the onion has turned black, which is the chemical effect produced by the onion after absorbing formaldehyde. When the onion is black, replace it with a fresh one, repeat it a few times, and it will remove formaldehyde well.

Remember that the onions must be changed frequently.

There is often a saying that after home decoration, there is no need for special treatment, as long as you buy a few pots of green plants, and then put some fruit peels like grapefruit at home, you can absorb the formaldehyde in your home. Experts warn everyone to stop believing in these sayings, sometimes not only will not have any effect, but will also have the opposite effect!

There are several misconceptions about removing formaldehyde, and these common misconceptions can sometimes cause more damage. For example, the so-called onion and grapefruit peel can remove formaldehyde, and many people believe that after chopping onions and orange peels, they can absorb formaldehyde in the home and purify the air in the house. But in fact, the smell of onions and orange peels is stronger, so it only covers up the pollutants, making people feel that formaldehyde has been removed, and in fact, the formaldehyde content in the home is still very high.

In this regard, I consulted an environmental expert with 16 years of research experience, and learned some tips for removing formaldehyde that are suitable for most families.

Good method 1: Ventilation is constant.

Frequent ventilation of the home can help alleviate formaldehyde pollution, and if the wind outside is strong, ventilation can reduce the concentration of formaldehyde for a while. However, if the wind outside is light, the ventilation effect is poor. In case of bad weather and cannot be ventilated, indoor formaldehyde will accumulate and threaten our health.

Therefore, we should use other good methods to carry out formaldehyde treatment together.

Good method 2: Put a little activated charcoal.

Activated carbon can adsorb a part of formaldehyde gas, which is a relatively primitive adsorption material. However, it cannot decompose formaldehyde gas, so as long as it adsorbs saturated, it will cause formaldehyde**. Generally, we use activated carbon and need to replace it once a month or so.

Good method three: use a little scientific method.

We must have heard of this formaldehyde removal material, and it is currently widely used in the environmental protection industry. Compared with other formaldehyde removal materials, it has a great advantage, that is, it can not only adsorb formaldehyde, but also decompose formaldehyde into harmless gases such as water vapor and volatilize into the air, so that Qiaoluoene can continue to adsorb formaldehyde, will not be saturated, and has a validity period of up to 3 years.

Good method four: place an air purifier.

The air purifier with activated carbon board can absorb formaldehyde gas at home, but you need to replace the activated carbon board regularly, otherwise it will adsorb saturation and cause formaldehyde secondary**. At the same time, you should also note that using an air purifier is very power-intensive.

Answer: Onions do not remove formaldehyde, they can only cover the odor because onions only contain water and other acidic, alkaline substances and can only absorb a small amount of pollutants in the air. Moreover, the use of onion and grapefruit peel are all folk soil methods, which have no scientific basis, so it is best to use other methods to remove formaldehyde, such as: activated carbon, air purifiers, etc.

Some people say that onions can remove formaldehyde, but in fact there is none, but the taste of onions is relatively strong, and the taste of onions covers the taste of formaldehyde, just like grapefruit peel, pineapple peel, etc., in fact, the effect of removing formaldehyde is not great. The principle of onion, orange peel, and grapefruit peel, which is often used to remove the smell of decoration, is that its molecule is larger than the formaldehyde molecule, so it can "cover" the smell but is not really adsorption. They may also react with formaldehyde and may produce other harmful gases.

You can put some greenery indoors, put the pot in the corner of the room, and the smell will soon be gone. It is also necessary to ventilate more, it is best to be able to ventilate for a few hours in the morning and evening, and then use formaldehyde scavengers, be sure to choose an air purifier that will not produce secondary pollution, if you feel that the effect is good, you can use it in large quantities, quickly remove formaldehyde and other harmful gases, and quickly remove odors. Therefore, if we want to get rid of the smell or formaldehyde smell in the room as soon as possible, the best way is to open the window so that the air in the room can circulate enough.

The effect is not very good, so it is also very good to keep the room ventilated and put a few more potted plants.

No. Formaldehyde is a chemical and cannot be dealt with simply by using natural plants - tea, onions, etc. Indoor ventilation, although it has a certain effect on improving indoor air, can not be expected to completely remove indoor pollution, indoor harmful gases exceed the standard, ventilation is useless.

The principle of onion, orange peel, and grapefruit peel, which is often used to remove the smell of decoration, is that its molecule is larger than the formaldehyde molecule, so it can "cover" the smell but is not really adsorption. Pineapple only reduces the smell of formaldehyde, formaldehyde is still volatile, "pineapple in addition to the smell of formaldehyde at the same time, will also have some reaction with formaldehyde, may cause other harm to the human body, onion and tea is the same".
