What are the uses of activated carbon?

Activated carbon is a porous carbon material widely used in fields such as air purification, water treatment, industrial catalysis, pharmaceuticals, and energy storage.

Air Purification and Gas Adsorption

With its abundant microporous and mesoporous structure, activated carbon efficiently adsorbs harmful gases and volatile organic compounds (VOCs) from the air; it is commonly used in air purifiers, exhaust gas treatment, formaldehyde removal, and industrial waste gas control. Coconut shell activated carbon is particularly well-suited for adsorbing small-molecule gases due to its high adsorption capacity, making it a frequent choice for high-end air purification applications.

Water Treatment

Activated carbon is extensively used in water treatment to remove odors, residual chlorine, organic pollutants, and heavy metal ions from tap water and drinking water. Powdered activated carbon is commonly used for liquid-phase decolorization and water purification, whereas granular activated carbon is suitable for continuous-flow water treatment systems.

Industrial and Chemical Applications

Activated carbon serves as a catalyst or catalyst support in industrial processes such as chemical reactions, solvent recovery, and the synthesis of vinyl chloride and vinyl acetate. Coal-based and wood-based activated carbons are widely used for industrial adsorption and decolorization, offering selective adsorption capabilities for substances of varying molecular weights.

Medicine and Health

In the medical field, activated carbon is used for detoxification and the adsorption of toxins or overdose medications; powdered activated carbon can serve as an oral adsorbent. Its hydrophobic nature and porous structure enable it to adsorb a wide range of organic and inorganic substances, aiding in the treatment of poisoning and digestive disorders.

Energy and New Materials

Activated carbon is also utilized in high-tech sectors such as energy storage, electrode materials, and precious metal recovery. Its high specific surface area and renewable nature make it highly valuable for environmental protection and sustainable energy applications.
