  • What Is Activated Charcoal and How Does it Work

     · Activated charcoal is carbon that has been treated with oxygen.The treatment results in highly porous charcoal. These tiny holes give the charcoal a surface area of 300-2 000 m 2 /g allowing liquids or gases to pass through the charcoal and interact with the exposed carbon. The carbon adsorbs a wide range of impurities and contaminants including chlorine odors and pigments.
