What is the principle of charcoal adsorbing toxic gases? Why should used charcoal be dried?

Principle: Activated carbon is a porous carbonized substance with extremely rich pore structure and good adsorption characteristics. Its adsorption is formed by physical and chemical adsorption forces, and its appearance is black. In addition to the main carbon, it also contains a small amount of hydrogen, nitrogen and oxygen, and its structure looks like a hexagon. Because of the irregular hexagonal structure, it has the characteristics of many bodies and high surface area. The specific surface area per gram of activated carbon is equivalent to 1000 square meter.

1. It exists in molecular form.

2. It depends on the adsorption capacity.

3. If it is to absorb the smell of indoor decoration, it is best to expose to the sun for about 3 days, and the high temperature will better accelerate the volatilization of toxic gases in charcoal.

You don't have to make it yourself, just buy it, and you can find it in the labor insurance store. It's not expensive and it's very cheap. Coconut shell activated carbon is better for home use.
