Activated Carbon & Charcoal Frequently Asked Questions

Activated carbon is a highly porous substance that attracts and holds organic chemicals inside it. The media is created by first burning a carbonaceous substance without oxygen which makes a carbon “char”. Next, the “char” is treated chemically or physically to develop an interconnected series of “holes” or pores inside the carbon.

Frequently Asked Questions About Activated Charcoal & the

What is activated charcoal? The simple answer: it is the charcoal made from different sources such as wood, coconut shell, bamboo, or coal, that is then “activated”, with steam or acid. This process carves away the internal structure of the charcoal particles producing a much higher [internal] surface area.

Activated carbon Wikipedia

Activated carbon, also called activated charcoal, is a form of carbon processed to have small, low-volume pores that increase the surface area available for adsorption or chemical reactions. Activated is sometimes replaced by active.. Due to its high degree of microporosity, one gram of activated carbon has a surface area in excess of 3,000 m 2 (32,000 sq ft) as determined by gas adsorption.
