[0002] Activated carbon is a specially treated carbon. Organic raw materials (fruit shells, coal, wood, etc.) are heated in an airtight condition to reduce non-carbon components (this process is called carbonization), and then react with gas, the surface is eroded, and a structure with developed micropores is produced (this process is called activation). Since the activation process is a microscopic process, that is, the surface erosion of a large number of molecular carbides is point erosion, so the surface of activated carbon has countless tiny pores. The diameter of the micropores on the surface of activated carbon is mostly between 2 and 50nm. Even a small amount of activated carbon has a huge surface area. The surface area of ​​each gram of activated carbon is 500 to 1500m2. Almost all applications of activated carbon are based on this feature of activated carbon.
