A porous form of carbon that acts as a powerful adsorbent, used to decolourise liquids, recover solvents, and remove toxins from water and air.
In waste treatment, it is used to remove dissolved organic matter from waste drinking water. It is also used in motor vehicle evaporative control systems.
Usually found in small pellets so that the surface area is greater than a large chunk of it. Pores on each pellet increase the surface area further. The greater the surface area means the greater ability to absorb.
