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 is a porous carbon containing substance with a well-developed pore structure and a huge specific surface area. These pore structures include micropores, mesopores, and macropores, which endow activated carbon with extremely strong adsorption performance. Granular activated carbon has a wide range of raw materials, such as wood, fruit shells, coal, etc., which are made by high-temperature carbonization and activation treatment.
