what is activated carbon


 Activated carbon is one of the most effective media for removing a wide range of contaminants from industrial and municipal waste waters, landfill leachate and contaminated ground. As the world’s most powerful adsorbent, it can cope with a wide range of contaminants.Different contaminants may be present in the same discharge and carbon may be used to treat the total flow, or it may be better utilized to remove specific contaminants as part of a multistage approach.


Carbon Activation
Activated carbon is made from any substance with a high carbon content, and activation refers to the development of the property of adsorption. Activated carbon is important in purification processes, in which molecules of various contaminants are concentrated on and adhere to the solid surface of the carbon. Activated carbon is generally nonpolar, and because of this it adsorbs other nonpolar, mainly organic, substances. Extensive porosity (pore volume) and large available internal surface area of the pores are responsible for adsorption.


Any inexpensive material with a high carbon content and a low inorganic content can be used as potentialraw material in producing activated carbons. The most often used raw materials for manufacturing activated carbons include wood, peat, bituminous coal, lignite, coconut shell, nutshells, lignin, and others.

Activated carbons can be manufactured by either a physical or a chemical activation process. The physical activation process generally is used to manufacture activated carbon in a two-step activation process—the carbonization of raw materials in the absence of O2 followed by the activation of carbonized products. Steam and carbon dioxide (CO2) are the activating reagents most commonly used in physical activation, significantly influencing the porosity of the activated carbons.  The chemical activation process is used to manufacture activated carbons usually in a single step, using zinc chloride, phosphoric acid, and potassium hydroxide as the activating reagents.


The carbonaceous materials are converted into activated carbons depending upon the nature of the raw materials, the nature of the activating reagent, and the conditions of the activation process.Furthermore, activated carbon can be impregnated with sulfur (S), chloride, or iodine to increase its adsorptive capacity, making the impregnated activated carbon much more effective than un-impregnated activated carbon for removing gaseous mercury (Hg) from flue gases at low temperatures.
