Activated carbon has the surface area of the unit if the volume is from 500 to 2500 m2 / g ( take a specific example to compare the tennis courts have a wide area of approximately 260 m2 ) . This very large specific surface as a consequence of the hollow fiber structure that is mostly inherited from the organic material originating through dry distillation process ( drying ) at high temperature in anaerobic conditions . Most of the empty spots - cracked circuit , the pull thurat are strong and they play a role in the transmission slot ( Connect ) .
Activated charcoal is often manually upgrade ( for example , ash washed or coated surface chemistry ) , to retain the suction filter properties , so absorbency can be special components such as heavy metals .
Significant increases Properties of activated carbon also in terms of it 's non-toxic (even when it was ingested ) , activated charcoal is made from wood and coal prices are usually low , from coir , fruit peel the high cost and better quality . Waste of process manufacturing activated carbon is easily destroyed by combustion method . If such substances are filtered , the heavy metal recovered from combustion ash , is also very easy .
