What is the structure of activated carbon?
Activated carbon is a black powder or granular amorphous carbon. The main components of activated carbon in addition to carbon and oxygen, hydrogen and other elements. Because of the irregular arrangement of the activated carbon on the structure, there are pores in the cross connection, and the carbon tissue defects will occur in the activation. Therefore, it is a kind of porous carbon, which has low bulk density and large specific surface area.
Activated carbon porous, so the surface area is very large, a cubic centimeter of adsorption area of about one thousand square meters.
The activated carbon is produced by the high temperature heating of the carbon through the isolated oxygen.
