What do you know about activated carbon?<\/strong><\/h1>\n\n\n\n

Activated carbon or activated carbon filter are concepts that are not too strange to us. However, in reality, not everyone understands the structure, mechanism of action as well as practical benefits that activated carbon brings. Therefore, the following article will help you answer most questions about a concept that is becoming more and more familiar in daily life.  <\/em><\/p>\n\n\n\n

1. What is activated carbon?<\/strong><\/h2>\n\n\n\n

Activated carbon is a form of carbon that is processed to have high porosity, with many small cracks and pores. With such a structure, the surface area is larger, making it easier to absorb or enhance chemical reactions. Activated carbon is created from burning fuels with many carbon components such as wood, and coal, ... at high temperatures up to 900 degrees Celsius.<\/p>\n\n\n\n

3. The mechanism of action of activated carbon<\/strong><\/h2>\n\n\n\n

Through cracks, small holes from activated carbon will easily absorb impurities, dirt, and pollutants such as chlorine, and benzene in water or SO2, CO2, and H2S gas in the air. These substances will adhere to the surface of the carbon, with the larger the surface area of \u200b\u200bthe activated carbon, the stronger the attraction of impurities will be.<\/p>\n\n\n\n

4. Uses of activated carbon<\/strong><\/h2>\n\n\n\n

Thanks to its ability to absorb, activated carbon is used for many uses such as: <\/p>\n\n\n\n

 4.2 Exhaust gas treatment, deodorization<\/strong><\/h3>\n\n\n\n

Activated carbon is often used for deodorizing widely in kitchen deodorizers, and deodorizing in waste treatment. In addition, activated carbon also deodorizes, disinfects air conditioners, or treats industrial exhaust gases.<\/p>\n\n\n\n

4.3 Medical use<\/strong><\/h3>\n\n\n\n

In addition to the above uses, activated charcoal also treats symptoms such as flatulence, diarrhea, stomach pain, .... by absorbing harmful substances in the body and excreting them outside through the digestive tract...<\/p>\n\n\n\n

4.4 Industrial use<\/strong><\/h3>\n\n\n\n

In industry, activated carbon is often present in the final metal processing stage. Typically used in the purification of electroplating solutions. Activated carbon also has applications in the mining industry to extract and filter gold, silver and other precious metals.<\/p>\n\n\n\n
