Can bamboo charcoal remove formaldehyde?

The smell of formaldehyde is poisonous, and there are many ways to remove formaldehyde in life, but many of these methods are questioned. Whether they can remove formaldehyde remains to be investigated. Some methods of removing formaldehyde only have the effect of removing odors, but cannot really remove formaldehyde. In fact, bamboo charcoal can remove formaldehyde, but adsorption does not mean absorption, so bamboo charcoal needs to be replaced in time.

To remove the pungent formaldehyde in newly renovated houses, many people expect to rely on bamboo charcoal with good adsorption effect. Although bamboo charcoal does have a certain adsorption effect, many people exaggerate the effect of bamboo charcoal. Bamboo charcoal has a certain adsorption effect on formaldehyde, but the adsorption capacity is stable and easily changed by environmental changes. It is not even as tightly combined with water molecules. To put it simply, if there is more moisture in the room, bamboo charcoal will also absorb moisture, and when it reaches saturation, it can squeeze out the formaldehyde adsorbed on the bamboo charcoal.

What are the effective methods to remove formaldehyde?

1. Activated carbon adsorption

Activated carbon is a relatively cheap and practical method for removing formaldehyde. It is characterized by physical adsorption, which is thorough and not prone to secondary pollution. The physical effect of activated carbon is deodorization and detoxification; it does not contain any chemical additives and has no effect on the human body.

The method after decoration is to use products with powerful formaldehyde capture, adsorption and elimination functions. Using high-tech nano and nano modification technology, after multiple screening, formulation and activation modification, several natural nano-scale raw materials are combined with conventional oxidants to effectively remove harmful gases such as formaldehyde, ammonia, benzene, carbon monoxide, etc. in the living environment. It is not only effective in removing formaldehyde, but also in removing harmful substances such as ammonia, benzene, TOVC, etc. This method can be used if a moderately excessive amount of electricity is placed in an area of ​​30 square meters.

3. Ventilation method to remove formaldehyde

Through the circulation of indoor air, the content of harmful substances in the indoor air can be reduced, thereby reducing the harm of such substances to the human body. In winter, people often close doors and windows, and the air cannot circulate between indoor and outdoor spaces. Not only will the formaldehyde content in the indoor air increase, but radon gas will also continue to accumulate and even reach a very high concentration.

Soak 300 grams of black tea in two basins of water, put it in the room, and open the windows for ventilation. Within 48 hours, the indoor formaldehyde content will drop by more than 90%, and the irritating smell will be basically eliminated.

5. Plant deodorization method

Plant decontamination can be chosen for medium and low pollution: In general, in environments where indoor environmental pollution is light or moderate, and the pollution value is less than 3 times the national standard, plant purification can achieve relatively good results. Choose and place plants according to the different functions and size of the room. Generally speaking, it is more appropriate to place two pots of 1.5-meter-high plants in a room of about 10 square meters. (Recommended indoor pollution control method: ventilation + activated carbon + formaldehyde-removing plants, suitable for medium and low pollution) Select and place plants according to the different functions and size of the room. Generally speaking, it is more appropriate to place two pots of 1.5-meter-high plants in a room of about 10 square meters.
