In this work, activated carbon was produced by chemical activation with phosphoric acid of agricultural wastes such as Arecanut shell of 180 mesh. Activated carbon is produced at activation temperature of 400 ºC by slow pyrolysis. The BET surface area and iodine number surface area was calculated and compared. The FTIR spectrum showed the presence of activated carbon. Thermogravimetric analysis revealed that the activated carbon is thermally stable at 480 ºC. The SEM images showed the incorporation of activated carbon particles. Surface area plot shows the details of morphological change caused by feret diameter on iodine number surface area, iodine number, methylene blue number and acid adsorption value. These results proves that the feret diameter plays important role in selection of final activation temperature and impregnation ratio, and also important in determining the quality of activated carbon obtained.
