Abstract: The paper presents results of a study on obtaining activated carbon from Albizia lebbeck and on its use as adsorbent. The plant was abundantly found in tropical area. The effects of activation temperature of the activated carbon were studied. It was found that significant weight losses occurred during the activation process due to a continual release of volatile matter and carbon burn-off through weak carbon –CO2 oxidation, resulting in an increase of solid density and a decrease of apparent density. Hence, the activated carbons prepared from the stem of Albizia lebbeck possessed well-developed porosities, which were verified by Scanning Electron Microscopy (SEM). The nature of the compound can be identified by X-ray diffraction (XRD). The development of micro porosity of the Albizia lebbeck carbon would leads to potential applications for the removal of metal ions. This could be elucidated by the surface functional groups of the Albizia lebbeck carbon, as detected by Fourier Transform Infrared Spectroscopy (FTIR).
Keywords: Activated carbon, SEM, XRD, FT-IR.
