Activated carbon and activated charcoal are the same substance. "Activated Carbon and" and "Activated Charcoal" are synonyms in Chinese and are used to refer to a specially treated carbon material with a large specific surface area and a highly porous structure.
Activated Carbon/activated charcoal is an adsorbent widely used in various fields. It is produced from natural carbonaceous substances (such as wood, plant residues, etc.) or ore minerals, and is prepared by carbonization and activation (usually phosphoric acid or steam treatment).
This treatment process makes activated carbon/activated charcoal have many tiny pores, which increases its surface area and enables it to adsorb a large amount of substances. The adsorption capacity of Activated Carbon/activated carbon mainly comes from its porous structure, and gas, liquid or dissolved substances are adsorbed on its surface through physical adsorption.
Activated Carbon/activated charcoal is widely used in water treatment, air purification, food industry, pharmaceutical, chemical, environmental protection and other fields. It can absorb harmful substances, odors and organic substances, and is used to remove residual chlorine, heavy metals, drug residues and other substances in water, as well as purify harmful gases and particles in the air.
All in all, Activated Carbon and activated charcoal are the same substance and are used interchangeably in Chinese. They both refer to specially treated carbon materials with large specific surface area and highly porous structure, which are often used in adsorption and purification applications.
