1. Depending on its unique pore structure, activated carbon is a kind of microcrystalline carbon material mainly made of carbon containing materials with black appearance, developed internal pore structure, large specific surface area and strong adsorption capacity. There are a large number of invisible micropores in activated carbon materials. There are micropores in 1g activated carbon materials. After unfolding, the surface area can be as high as 800-1500 square meters, which is higher for special purposes. In other words, in an activated carbon particle the size of a rice grain, the inner surface area of the micropore may be equivalent to the area of a living room. It is these highly developed pore structures, such as human capillaries, that make activated carbon have excellent adsorption properties.
2. The force of mutual adsorption between molecules is also called "van der Waals gravity". Although the speed of molecular motion is affected by temperature and material, it is always moving in the microenvironment. Due to the mutual attraction force between molecules, when a molecule is captured by the inner pores of activated carbon and enters the inner pores of activated carbon, due to the mutual attraction between molecules, more molecules will be attracted until the inner pores of activated carbon are filled.
