The adsorption performance of activated carbon mainly comes from its highly developed pore structure and huge specific surface area. These pores can effectively adsorb organic matter, chromaticity, odor, residual chlorine and other substances in water, as well as toxic and harmful gases in the air. The adsorption process of activated carbon is usually non selective and can adsorb various substances, but it can also be selectively adsorbed through specific treatments.

The raw materials for activated carbon are very diverse, mainly including fruit shells (such as coconut shells, peach shells, apricot shells, jujube shells, etc.), wood, coal, petroleum coke, etc. These raw materials undergo high-temperature carbonization and activation treatment to form activated carbon with rich pore structure and huge specific surface area. Activated carbon is a powerful porous carbon containing substance with a huge specific surface area and highly developed pore structure. It can adsorb various substances and is widely used in multiple fields.
