Activated carbon
Activated carbon, also called activated charcoal or activated coal, is a general term which covers
carbon material mostly derived from
charcoal. For all three variations of the name, "activated" is sometimes substituted by "active". By any name, it is a material with an exceptionally high
surface area. Just one
gram of activated carbon has a surface area of approximately 500 m2, typically determined by
nitrogen gas
adsorption, and includes a large amount of microporosity. Sufficient activation for useful applications may come solely from the high surface area, though often further chemical treatment is used to enhance the absorbing properties of the material.
