Prized for its extremely porous surface area, the superior performance of activated carbon as an adsorbent lends itself to a number of applications spanning across a range of industries.. One of the major benefits to activated carbon is that it is capable of being restored, meaning that "spent" carbon, or carbon saturated with the adsorbed components, can be desorbed of the components to
