Activated carbon is a porous carbon-containing material, it has a highly developed pore structure, is a very good adsorbent, activated carbon adsorption area per gram equivalent of eight tennis and drinking places much more, while its adsorption is by reached by the physical adsorption and chemical adsorption. Its composition of the material in addition to carbon elements, still contains a small amount of hydrogen, nitrogen, oxygen and ash, which form a six-carbon ring structure was made of material accumulation. For the six ring carbon irregular arrangement, resulting in a microporous activated carbon volume and high surface area.
