Activated carbon is a kind of carbon material with great specific surface area and strong adsorption and decolorization ability. In the 19th century, people used it to decolorize, taste and purify sugar, wine and water. Bone charcoal has been used for water filtration for more than 100 years. Activated carbon was used to make gas masks during the first World War. By the 1990s, it was widely used in sewage treatment, concentration and recovery of organic solvents, air purification and other environmental protection, gold extraction and other fields.
