The pores of bamboo charcoal are dominated by large holes, while activated carbon is large, physical activated activated carbon is dominated by micropores, and chemical activated activated carbon is dominated, and the active carbon produced by different activation processes is not same. Bamboo charcoal is mainly adsorbing some macromolecular substances, including many microorganisms. The activated carbon has different pore structures and is applied to different fields depending on the adsorption species. However, the adsorption of activated carbon is stronger than the bamboo charcoal of the substance (such as a harmful gas such as formaldehyde, benzene, ammonia, etc.) having a small diameter. Moreover, the active carbon adsorption is highly targeted, and the different apertures are used to adsorb different substances.
