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. The following is most popularly described and used as an absorber of contaminants including 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 method involves a process called carbonization. In this process, carbon content is heated up to 600-900 ?C, in an atmosphere of inert gases such as argon or nitrogen. Another method, called Oxidation, exposes the carbonized materials to oxidizing atmospheres such as oxygen, carbon dioxide, or steam, at temperatures between 600-1200 ?C. To have a larger surface area capable of reactions / absorptions of chemicals to occur can be obtained by altering the molecule's structure.

Activated carbon can be created in a variety of different physical forms. Powdered activate carbon has a large surface area to volume ratio and is generally used in raw water intakes, rapid mix basins, clarifiers, and gravity filters. Granular activated carbon is larger than the powdered version and, consequently, has a smaller surface area to volume ratio. It is preferential to use this item to absorb gases or 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. The goal of removing pollutants and other contaminates is the same during the entire process of activated carbon which make take many variances of forms.

How does activated carbon work in purification? Let us consider the Britta water filters, which are used for cleaning the tap water in homes. As tap water goes through the filter, organic elements are captured by the active carbon and the the two elements will combine and become a new element. The pollutants never get into your sink or the glass because the pores of the filter never allow such large molecules to pass through.

The main features of activated carbon have been explained and it will be now in your knowledge what is the procedure for its production, and how it works. You will also be aware of the physical forms which can be taken by it and what are its purposes. Also consider activated charcoal.
