Activated carbon, also called activated charcoal, activated coal, or carbo activatus, is a form of carbon processed to be riddled with small, low-volume pores that increase the surface area available for adsorption or chemical reactions.[1] Activated is sometimes substituted with active.
Due to its high degree of microporosity, just one gram of activated carbon has a surface area in excess of 500 m2, as determined by adsorption isotherms of carbon dioxide gas at room or 0.0 °C temperature. An activation level sufficient for useful application may be attained solely from high surface area; however, further chemical treatment often enhances adsorption properties.
Activated carbon is usually derived from charcoal.
How Activated Carbon Works
Activated carbon works by adsorption – the process by which a gas bonds to the surface of a solid. In this case, the solid is the activated carbon, which adsorbs as much as 60% of its weight in airborne pollutants. Air passes through the filter where airborne gases, chemicals, and odors react chemically with the surface of the carbon, effectively sticking to it. The clean air then flows out of the filter. Activated carbon filters will adsorb even a small amount of almost all vapors and they have a large capacity for removing organic molecules like solvents. They can also simultaneously adsorb many different kinds of chemicals, making these filters very efficient. Activated carbon works in any temperature or humidity and isn’t toxic, so it’s safe for people to handle. Thankfully, it’s also quite affordable.
