Activated carbon, also known as activated charcoal, is a highly porous material that is produced by treating carbon-rich organic materials, such as wood, coconut shells, or peat, with heat and chemicals to create a network of pores and a large surface area. This high surface area and porosity make activated carbon an excellent adsorbent for a wide range of substances, including organic molecules, gases, and liquids. It is widely used in various applications, such as water treatment, air purification, food and beverage processing, and medical treatments.
