export@zzzkelin.comColumnar activated carbon is an effective material for air purification due to its high surface area and adsorption capacity. Its raw material is coal, and coal-based activated carbon is made by heating carbonaceous materials in the presence of an activator to form a porous structure with a large internal surface area.
