In this work, the produced activated carbons were characterized by Nitrogen Adsorption Theorem and Scanning Electron Microscope instruments. The optimal activation conditions were found at temperature of 500°C and at activation time of 180 min. Result showed that the BET surface area, total pore volume and diameter of the activated carbon were 1288.52 m2 g-1, 0.81 cm3 g-1 and 2.49 nm, respectively. From the nitrogen adsorption-desorption isotherm and pore size distribution, it was found that vast majority of pores fall within range of mesopore, therefore indicating that activated carbon prepared from rubber-seed shell is an attractive source for liquid and gas adsorption applications.]]>Bukallah, S.B., M.A. Rauf and S.S.
