Caption: Activated carbon. Activated carbon is charcoal that has been treated with oxygen to expose millions of tiny pores between carbon atoms. It is also called activated charcoal or activated coal and is a general term that designates carbon material primarily derived from charcoal. The opening of tiny pores increases the surface area of the carbon. These micropores provide superb conditions for adsorption to occur, since adsorbing material can interact with many surfaces simultaneously. The active or activated charcoals (carbon) are widely used to adsorb odorous or colored substances from gases or liquids. When certain chemicals pass next to the carbon surface they attach to the surface and are trapped. Activated carbon is used in gas purification, metal extraction, water purification, medicine, sewage treatment, air filters in gas masks and filter masks, filters in compressed air and many other applications. Activated carbon has become the treatment of choice for many poisonings, and other decontamination methods for binding of the toxin to prevent stomach and intestinal absorption.
