ABSTRACT
Aim: This study was carried out find the feasibility of utilizing raw mango seed coat under various process conditions to produce the best activated carbon by chemical activation and compared with commercial activated carbon. Methodology: Activated carbon was produced by chemical activation under various process conditions such as different activation temperatures, activating agents, impregnation volume percentages and activation times for pyrolysis in a programmable electrical furnace with reactor in the absence of air. Results: The results were compared using phosphoric acid having 50% impregnation volume to other activating agents, the activating temperature was 400oC, activation time 1 hr, iodine number, methylene blue number, % yield and B.E.T surface area being 831 mg g-1, 212 mg g-1, 41.09% and 1114 m2 g-1 respectively. Interpretation: Carbon samples prepared using mango seed coat treated by H3PO4, showed clear open porous structures along with a larger pore size compared to commercially available activated carbon.
