Activated Carbon has a wide range of applications, such as: decolorization of sugar, military gas masks, cigarette filters, air purifiers, tap water treatment, drinking water purification, detoxification, sobering, pollution control of radioactive elements, reduction of residual pesticides in soil, soil conditioning , Governance indoor formaldehyde, vegetable preservation, and so on. This is mainly because:
The unique pore structure of activated carbon itself
Activated carbon is a type of microcrystalline carbon material that is mainly made of carbonaceous material and has a black appearance, a developed internal pore structure, a large specific surface area, and a strong adsorption capacity. Activated carbon materials have a large number of microscopic pores invisible to the naked eye. One gram of activated carbon material has micropores, and its surface area can be as high as 800-1500 square meters after unrolling, which is even higher for special applications. That is, in a rice grain-sized activated carbon granule, the internal surface area of the micropore may be equivalent to the size of a living room area. It is these highly developed, such as human capillary-like pore structure, so that activated carbon has excellent adsorption properties.
