Carbon samples were activated chemically and by thermal means (400-1000 °C). The samples were characterized by surface area, EDS analysis showed high carbon contents in the samples activated at high temperature as compared to raw and 400 oC activated samples while the content of oxygen was found to decrease with the increase in activation temperature. Other elements like, chlorine, silica, iron, magnesium etc were found in trace amounts. The XRD analysis using ORIGIN-50 computer software showed that carbon, hydrogen, nitrogen, oxygen. boron, chromium, fluorine and nitrogen were present in the carbon samples.
