Activated carbons were prepared from jute stick by chemical activation using ZnCl2, H3PO4, and H2SO4. The influence of activating agents and carbonization temperatures ranging from 300oC ~ 350oC were studied. The properties of the carbons were characterized by iodine adsorption and the Fourier-transform infrared spectroscopy (FT-IR) method. The results of iodine tests showed resemblance close to the values found in literature 500~1200 (mg/g). FTIR results revealed the existence of O-H, C=O, C=C, C-O and C-H bonds.
