Activated
carbon is a material that is produced from carbonaceous source materials, such
as coal, coconuts, nutshells, peat, wood,
and lignite.
The
primary raw material used for activated carbon is any organic material with a
high carbon content. The carbon-based material is converted to activated
carbon through physical modification and thermal decomposition in a furnace,
under a controlled atmosphere and temperature.
The finished product has a large surface area per unit volume and a network of submicroscopic pores where adsorption takes place.
