Can bamboo charcoal bags absorb formaldehyde?

Formaldehyde is very harmful to the human body, but this substance is often used in decoration. Generally speaking, after decorating a house, the first task is to remove formaldehyde. There are many substances that can remove formaldehyde, and everyone certainly wants to choose the one with the best effect. Bamboo charcoal bags are said to have a strong ability to remove formaldehyde. So, can bamboo charcoal bags absorb formaldehyde? Let’s take a closer look.

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 affected by environmental changes. It is not even as tightly combined with water molecules. To put it simply, if there is too much 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.

The presence of formaldehyde mostly comes from the volatilization of chemicals. Especially after a newly renovated house has a strong smell, it proves the presence of formaldehyde. Formaldehyde is a toxic gas, so try not to rush into a newly renovated house. The most effective way to remove formaldehyde is to ventilate the house. You can also place some green plants that absorb these gases in the house, such as aloe vera and spider plants. These plants can use the absorbed formaldehyde as raw materials for synthesizing organic acids, sugars and amino acids, which is beneficial to human health.

The difference between activated carbon and bamboo charcoal

1. Different processing technology

Bamboo charcoal only goes through the carbonization stage, while activated carbon, in addition to the carbonization process, also goes through the activation stage.

2. The hardness is quite different

Bamboo charcoal has high density, high hardness, and is not easy to break, making it suitable for wear-resistant home textile products; while activated carbon has a light specific gravity, is soft, and is easy to break, so it is not suitable for products with high requirements for wear resistance.

3. Production costs vary widely

Bamboo charcoal only requires one carbonization process, while activated carbon also requires an activation process. Its cost is much higher than bamboo charcoal, about 3-5 times that of bamboo charcoal. Therefore, the product price is 3-5 times higher than activated carbon.

4. Different shapes

Bamboo charcoal comes in various forms, including cylindrical charcoal, flake charcoal, crushed charcoal, granular charcoal, charcoal powder, etc. It has a wide range of uses. For example, cylindrical charcoal can be made into various handicrafts, and charcoal flakes can be used for purifying water and cooking, etc.; while activated carbon generally only has two types, powdered form. Since there is no large block of activated carbon, its application is greatly limited.

5. There are differences in adsorption objects

The pores of bamboo charcoal are mainly macropores, while those of activated carbon are mainly micropores. Therefore, the types of substances that bamboo charcoal can adsorb are much wider than those of activated carbon, including many microorganisms. However, activated carbon cannot adsorb many substances due to its very small pore size. But as far as substances with very small molecular diameters are concerned, the adsorption capacity of activated carbon is several times stronger than that of bamboo charcoal.
