The adsorption performance of activated carbon mainly comes from its highly developed pore structure and huge specific surface area. These pores can effectively adsorb organic matter, chromaticity, odor, residual chlorine and other substances in water, as well as toxic and harmful gases in the air. The adsorption process of activated carbon is usually non selective and can adsorb various substances, but it can also be selectively adsorbed through specific treatments.

The raw materials for activated carbon are very diverse, mainly including fruit shells (such as coconut shells, peach shells, apricot shells, jujube shells, etc.), wood, coal, petroleum coke, etc. These raw materials undergo high-temperature carbonization and activation treatment to form activated carbon with rich pore structure and huge specific surface area. Activated carbon is a powerful porous carbon containing substance with a huge specific surface area and highly developed pore structure. It can adsorb various substances and is widely used in multiple fields.

In the pharmaceutical industry, granular activated carbon can be used to extract pigments, impurities, etc. from drugs, improving the purity of drugs. Granular activated carbon can be used in the field of metal recovery, adsorbing metal ions and achieving the recycling and reuse of metals. In the military and civilian fields, granular activated carbon can be used to make filter layers for gas masks, filtering out toxic substances in the air.

Granular activated carbon has a wide range of applications in water treatment, such as tap water purification, industrial wastewater treatment, electroplating wastewater treatment, etc. It can remove harmful substances from water and improve water quality. Granular activated carbon can be used in air purification equipment to adsorb toxic and harmful gases in the air, such as formaldehyde, benzene, ammonia, etc., and improve indoor air quality.
