activated carbon

n
(Elements & Compounds) a porous highly adsorptive form of carbon used to remove colour or impurities from liquids and gases, in the separation and extraction of chemical compounds, and in the recovery of solvents. Also called: activated charcoal or active carbon

ac′tivated car′bon



n.
