Activated Carbon

Activated Carbon is a black powder or block, granular, honeycomb amorphous carbon, but also a regular arrangement of crystalline carbon. In addition to carbon, activated carbon also contains two types of admixtures: one is a chemically bound element, mainly oxygen and hydrogen, which are left in the charcoal due to incomplete carbonization, or are foreign in the activation process. Non-carbon elements are chemically bonded to the surface of activated carbon; another type of admixture is ash, which is the inorganic part of activated carbon, and ash can easily cause secondary pollution in activated carbon. Activated carbon is widely used in production and life due to its strong adsorption.
