Activated charcoal is pure carbon comprised of millions of tiny micropores which have a large surface area. Just one gram of activated carbon has a surface area in excess of 3,000 m2. This high degree of microporosity makes it extremely effective in binding to vast amounts of organic material. Used for thousands of years for its adsorbing (bonding) properties, it is still the most widely used drawing substance available today. This is why charcoal is found in water filters and used to treat acute poisoning in hospitals around the world as an emergency decontaminant.
