Activated Carbon (Activated Carbon) is a granular material or powder derived from material containing carbon as coal, coconut shell, and so on. With certain processing that is the activation process such as treatment with high pressure and temperature, can be obtained activated carbon has a surface in wide. Charcoal is a porous solids containing 85-95% carbon, produced from materials containing carbon by heating at high temperatures.
In one gram of activated carbon, generally has a surface area covering 500-1500 m2, making it very effective in capturing particles of very fine size 0.01-0.0000001 mm. Activated carbon is a very active and will absorb any contact with the carbon. Within 60 hours of the activated carbon is usually widened saturated and no longer active. Therefore, it is usually activated carbon packed in airtight packaging. To a certain extent some types of activated carbon can be reactivated again, though not infrequently suggested for disposables. Reactivation of activated carbon is highly dependent on the prior activation method.
