The structural investigations of a commercial activated charcoal were carried out using different techniques such as X-ray diffraction, thermal analysis, nitrogen adsorption and mercury porosimetry. X-ray diffraction study revealed that the activated charcoal is amorphous in nature and has micro-cystalline structure. The thermogravimetric study of activated charcoal showed that the weight loss occurred in two distinct regions: one endothermic (dehydration) and other exothermic (combustion). The moisture and ash contents were found to be 11% and 10% respectively. The pore size distribution curve and DR analysis of nitrogen adsorption isotherm indicates the microporous nature of the activated charcoal with surface area 1000 m(2)/g, porosity 75.74% and pore volume 1.43 cm(2)/g.
