activated carbon

[′ak·tə‚vād·əd ′kär·bən]
(materials)
A powdered, granular, or pelleted form of amorphous carbon characterized by very large surface area per unit volume because of an enormous number of fine pores. Also known as activated charcoal.

activated charcoal, activated carbon

Charcoal obtained by carbonizing organic material, usually in the absence of air; usually in granular or powdered form; highly effective in adsorbing odors in air or in removing colors in solution.
