Definitions for "Activated Carbon"
A granular medium material (available in granular, powdered or block form) produced by heating carbonaceous substances (coal) or cellulose bases (wood, coconut shells) in the absence of air. The carbon has a very porous structure and may be used as an adsorbent for organic matter and dissolved gases in water.
Any form of carbon characterised by high adsorptive capacity for gases, vapours or colloidal solids. The carbon or charcoal is produced by destructive distillation of wood, peat, lignite, nutshells, bones, vegetable or other carbonaceous matter, but must be activated by high temperature steam or carbon dioxide which creates a porous particle structure.
Some chemicals are attracted to fine carbon particles which are then filtered out.
