Jul 11, 2019· Activated charcoal is carbon that has been treated with oxygen.The treatment results in highly porous charcoal. These tiny holes give the charcoal a surface area of 300-2,000 m 2 /g, allowing liquids or gases to pass through the charcoal and interact with the exposed carbon. The carbon adsorbs a wide range of impurities and contaminants, including chlorine, odors, and pigments.

Charcoal is a lightweight black carbon residue produced by strongly heating wood (or other animal and plant materials) in minimal oxygen to remove all water and volatile constituents. In the traditional version of this pyrolysis process, called charcoal burning, the heat is supplied by burning part of the starting material itself, with a limited supply of oxygen.
