The application of activated carbon is very extensive. In the field of water treatment, it can be used to purify tap water, treat industrial wastewater, electroplating wastewater, etc., and improve water quality. In the field of air purification, activated carbon is used in equipment such as air purifiers and gas masks to adsorb toxic and harmful gases in the air and improve indoor air quality. In addition, activated carbon plays an important role in the pharmaceutical industry, metal recovery, and other fields.

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.
