Activated carbon, also called activated charcoal, is a form of carbon processed to have small, lowvolume pores that increase the surface area available for adsorption or chemical reactions. Activated is sometimes replaced by 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.

Activated carbon (also called activated charcoal, activated coal or active carbon) is a very useful adsorbent. Due to their high surface area, pore structure (micro, meso and macro), and high degree of surface reactivity, activated carbon can be used to purify, dechlorinate, deodorize and decolorize both liquid and vapor appliions.
