Due to rapid development and industrialization in many countries, the

levels of industrial pollution to the atmosphere have been steadily rising. One of

these problems is the emission of toxic gases, which can have catastrophic

effects on the environment and the general populace. Examples of some of these

sources of toxic gas pollutants are volatile organic compounds emission from

crystallized organic chemicals, printed materials, paints and coatings and dry

cleaning fluids. The availability of variety of Granular Activated Carbon (GAC)

samples in several countries, its versatility as an adsorbent and the recent

inroads into the regeneration of spent GAC samples for many cycles (Skinner et.

al.) have further boosted its application in air pollution monitoring and control.

Preparation of activated carbon

The principle of manufacturing carbonaceous adsorbents is the selective

removal of some groups of compounds from the suitable carbon containing

materials such as wood, peat, lignite (Allen et. al.), bituminous coal, coconut

shell, walnut shell, coke fines etc (Merchant et. al.). These raw materials are first

subjected to carbonisation, which is usually carried out in the absence of air at
