Volatile organic compounds (VOCs) are recognized as a source of air pollutants; they include most solvents such as thinner, degreasers, cleaners, lubricants, and liquid fuels . Removal of VOCs by lignocellulosic activated carbon has been studied by various researchers . Some modifications andimpregnation using selected chemicals onto activated carbon are required to increase the adsorption capacity and improve the selectivity of trapped organic compound. The preparation conditions and characteristics of activated carbon used in removal of VOC are tabulated in Table 7.
