Activated carbon, renowned for its strong adsorption, large surface area, and excellent chemical stability, is widely used across various fields. The primary applications of activated carbon include:
Environmental Protection and Air Purification: Activated carbon is effective in removing toxic and harmful gases, as well as deodorizing and removing odors, such as preventing gasoline vapor loss and radioactive contamination.
Activated carbon is used to absorb harmful gases and odors in the air to improve air quality, commonly found in air purifiers, gas masks, and air filters for air purification.
Moreover, activated carbon can also be used for deep purification of drinking water, urban sewage treatment, and industrial wastewater treatment.
2. Food Industry: Activated carbon is used in the food industry to remove colors, odors, and unpleasant tastes, thereby improving the quality and texture of the food.
It is commonly used in the processing of syrups, juices, and alcoholic beverages for decolorization and refining, deodorization, removal of colloids, and improvement of stability.
3. Chemical and Pharmaceutical Industries: Activated carbon is used in the chemical industry for separating and purifying chemicals, as well as for adsorbing impurities. In the pharmaceutical industry, activated carbon can be utilized for selective adsorption and purification of antibiotics, probiotics, hormones, and alkaloids.
4. Mining and Atomic Energy Industry: Activated carbon is used in mining for the extraction of precious metals and rare elements. In the atomic energy industry, activated carbon can be utilized for helium purification.
5. Industrial Water Purification: Activated carbon can be used for purifying industrial water such as semiconductor integrated circuit products and pharmaceutical water.
6. Agriculture: Activated carbon can be used in agriculture as a long-lasting agricultural pesticide and soil amendment.
7. Gas Storage and Separation: Activated carbon is used for gas adsorption, storage, and separation, such as in the treatment of natural gas and H2.
In the tobacco industry, activated carbon is used as an adsorbent to reduce the content of some harmful substances in cigarette smoke and tobacco products.
Battery Manufacturing: Activated carbon can be used as electrode material for batteries, particularly in the application of electrochemical double-layer capacitors (supercapacitors).
Additionally, activated carbon is also used as a catalyst and as a catalyst carrier (such as activated carbon impregnated with copper, silver, zinc, molybdenum, and TEDA, etc., which is used in anti-toxic materials).
In summary, activated carbon finds extensive applications in environmental protection, food industry, chemical industry, pharmaceutical industry, mining, nuclear energy industry, industrial water purification, agriculture, gas storage and separation, tobacco industry, and battery manufacturing.
