What is Activated Carbon?
Activated carbon, also called activated charcoal, activated coal, or carbo activatus, is a form of carbon
processed to be riddled with small, low-volume pores that increase the surface area available for
adsorption or chemical reactions.[1] Activated is sometimes substituted with active.
Due to its high degree of microporosity, just one gram of activated carbon has a surface area in
excess of 500 m2, as determined by adsorption isotherms of carbon dioxide gas at room or 0.0 °C
temperature. An activation level sufficient for useful application may be attained solely from
high surface area; however, further chemical treatment often enhances adsorption properties.
Activated carbon is usually derived from charcoal
