Activated carbon (AC) has an important role in many life fields. It has high porosity and very useful for gas mixtures separation and purification of air and water. Every application requires specific properties of AC. Characteristics of AC are strongly influenced by raw material and parameters of manufacturing process. This paper is focused to characterize of activated carbons (ACs) derived from swat bamboo ( Gigantochloa verticillata ) which is manufactured under different carbonization temperatures. Prepared samples of swat bamboo were carbonized by heating variations of 550, 650 and 750°C and held at such temperature for 1 hour. Char yielded is powdered and meshed to maximum grain size of 250 u m and then physically activated by heating up to 800°C, held for 1 hour by flowing of 150 mL / min nitrogen. The results show that there was an increase in fix carbon and carbon contents from raw material to char and from char to ACs yielded; there were a little bit increase of fix carbon and carbon contents proportional to increasing of carbonization temperature. The maximum fix carbon (74.73%) and C (75.52) were obtained at carbonization temperature of 750°C. SEM observation showed that there has been a change in the morphology microstructure from raw material to activated carbons, wherein the ACs the pores structures clearly can be observed.
