Activated Carbon Information, News, and Activated Charcoal Products

I am sure that you, as well as the majority of people, don't have much knowledge about activated carbon and its various uses. Simply put, it is a processed form of carbon, which makes it extremely porous thereby increasing its surface area used for adsorbent or chemical reactions. This substance is used most often to absorb contaminants as well as pollution. After reading this, you should have a better idea of what activated carbon is and how it works.

There are a couple of ways that activated carbon can be produced from substances such as wood, nutshells, or coal. One way that is engrossed in the process known as carbonization.

The process requires heating of carbon content up to 600-900 C,and it has to be where the gases are inert such as argon or nitrogen in the atmosphere. Another method, called Oxidation, exposes the carbonized materials to oxidizing atmospheres such as oxygen, carbon dioxide, or steam, at temperatures between 600-1200 °C. The two methods physically change the molecular structure thus increasing the surface area available for the chemical reactions or activated carbon absorption to occur.

Activated carbon can be created in a variety of different physical forms. A large surface are to volume type of ratio can be found in powered activate carbon which is used generally, in water intakes, basins, rapid mix clarifiers, and filters such as gravity ones. The proportion of the face area to its capacity is comparatively less for activated grainy carbon when compared with the powdered one as the size of the former is bigger than the latter one. This substance is preferred in the adsorption of gases and vapors. Impregnated carbon, which name stems from being “impregnated” by several types of inorganic substances (Al, Mn, Zn, Fe, Li, Ca)The galleries and museums have been using it for the purpose of air pollution control. Activated carbon comes in several forms but it is used for the same purpose that is to get rid of pollutants and other toxic substances.

How does activated carbon work in purification? Let us consider the Britta water filters, which are used for cleaning the tap water in homes. When tap water passes through the filter, organic compounds are attracted to the activated carbon and the two substances chemically bond to one another. Molecules found in pollutants are too large to get beyond filter pores in your sink and therefore will never be found in your glass.

Now, you should have a better idea of how activated carbon is produced, the physical forms it can take, its purpose, and how it works. Don't forget to take note of activated charcoal.
