Activated Carbon

Activated carbon is purified, powdered charcoal. It is treated physically or chemically to generate microfissures that vastly increase its adsorptive surface area. The large surface area (500–1500 m 2 /g) and electrical charge effectively adsorb a wide range of polar compounds, notably phenols and their derivatives.
