Activated charcoal is a form of carbon that has been processed to increase its surface area and thus its adsorption capacity. It is made by heating charcoal in the presence of a gas, such as oxygen or steam. This process creates a porous structure with a high surface area, which allows the charcoal to adsorb a wide variety of molecules. Activated charcoal is used in a variety of applications, including water purification, air purification, and medical treatments.
Activated charcoal has been used for centuries to treat a variety of conditions, including poisoning, diarrhea, and flatulence. It is also used in water purification systems to remove contaminants such as chlorine, pesticides, and heavy metals. In addition, activated charcoal is used in air purification systems to remove pollutants such as smoke, dust, and odors.
