Activated Carbon Properties
Activated carbon is a porous material with excellent adsorption capacity, made from carbon-rich raw materials via carbonization and activation. Its most notable property is a large specific surface area (500-1500 m²/g), providing numerous adsorption sites. Its porous structure, including micropores, mesopores and macropores, enables effective adsorption of gases, liquids and impurities.
It has strong adsorption selectivity, especially for non-polar or weakly polar substances, following the "like dissolves like" principle. Besides, it is chemically stable, insoluble in most solvents, and maintains performance in a wide temperature range. It is also recyclable, reusable after thermal or vacuum regeneration, reducing costs and environmental impact. These properties make it widely used in water purification, air filtration and waste gas treatment.
