Activated carbons can be produced from the wastes of agricultural product. In this study oil palm shells were been use as the source to produce activated carbon using phosphoric acid. These wastes can be used by the industries to manufacture activated carbon. Carbonization and activation were done in the furnace using different temperatures which were 200°C for 15mnutes and 500°C for 45 minutes. Oil palm shells were impregnated with different concentration of phosphoric acid. The concentration of phosphoric acid that was used was 0M, 2M, 4M, 7M, 10M, and 12M. Several physical and chemical characterizations (moisture and ash, pH, iodine number, SEM, AAS, and methylene blue) of the prepared activated carbons were performed. An increase in the micropores with the increasing chemical shows that the development of porosity was also accompanied by a widening of the porosity as the amount of H3PO4 increased. The amount of iodine number and the amount of methylene blue adsorbed was increasing as the concentration of H3PO4 increased. The increase in adsorption process is due to the nature of pores on the surface of the activated carbons and throughout the surface of the carbons.
