Activated carbon is a specially treated carbon material with highly developed pore structure and large specific surface area, so it has strong physical adsorption and chemical adsorption capabilities. It is usually made of wood, coal and petroleum coke and other carbon-containing raw materials through pyrolysis and activation processing, and is widely used in air purification, water treatment, food processing, medicine, chemical industry and other fields.
The adsorption capacity of activated carbon is related to the pore size and structure. The smaller the particle, the faster the pore diffusion rate and the stronger the adsorption capacity. It is mainly used to remove organic pollutants, chemicals, heavy metals, colors and odors from water. Activated carbon can also be used for gas separation, solvent recovery, flue gas purification, desulfurization and denitrification and other industrial applications.
In water treatment, activated carbon can effectively remove residual chlorine, odor, color, etc., and improve water quality. It can also be used to remove harmful substances from the air.
