Activated carbon - Wikipedia

Activated carbon, also called activated charcoal, is a form of carbon processed to have small, low-volume pores that increase the surface area available for adsorption or chemical reactions. Activated is sometimes substituted with active.. Due to its high degree of microporosity, one gram of activated carbon has a surface area in excess of 3,000 m 2 (32,000 sq ft) as determined by gas adsorption.
