Activated carbon is porous carbon material. air purification

Activated carbon is porous carbon material. Due to its highly developed porous structure and huge specific surface area, Activated carbon has very strong adsorption capacity. Its pore varieties include micropores, mesopores and macropores of diameter <20A, 20-2000A and 2000A respectively. Activated carbon contains complicated oxygen surface functional groups. Activated carbon can also be impregnated with chemicals to produce impregnated activated carbons. Thus, it is not only used as an excellent adsorbent, but also used as a catalyst or catalyst carrier, to find wide applications in industrial production, agriculture, environmental protection, national intermediates, air purification, etc.
Activated carbon should be in accordance with China National Standards GB/7701-1997 Granular Activated Carbon from Coal. air purification
