activation process. The pores are due to the release of volatile matter and the reaction
between the chemical agent (sulphuric acid) and the carbon atom in precursor. From
the analysis of these surface images, it was concluded that the adsorbents under the
study were porous in nature and the pore development confirmed the sludge carbons
