Activated carbon has been explained in different ways by several authors. Marsh (1989)
defined activated carbon as porous carbon, which have been treated by oxidizing gases
during or after carbonization in order to increase porosity. Norlia Baharun (1999) defined
activated carbon as an organic material constituted basically by a graphitic structure.
While according to Benaddi (2000) stated that activated carbon is predominantly an
adsorbent with a large internal pore volume and surface are. Activated carbon can also be
defined as any porous material formed in the major part of carbon and characterized by a
well-developed porosity (6).
