Abstract − The activated carbon was produced from Sancheong bamboo by carbon dioxide gas activation methods. The carbonization of raw material was conducted at 900 oC, and CO2 activation reactions were conducted under various conditions: activation temperatures of 750-900 oC, flow rates of carbon dioxide 5-30 cm3/g-char·min, and activation time of 2-5 h. The yield, adsorption capacity of iodine and methylene blue, specific surface area and pore size distribution of the prepared activated carbons were measured. The adsorption capacity of iodine (680.8-1450.1 mg/g) and methylene blue (23.5-220 mg/g) increased with increasing activation temperature and activation time. The adsorption capacity of iodine and methylene blue increased with the CO2 gas quantity in the range of 5-18.9 cm3/g-char·min. But those decreased over those range due to the pore shrinkage. The specific volume of the mesopore and macropore of bamboo activated carbon were 0.65-0.91 cm3/g. Because of this large specific volume, it can be used to the biological activated carbon process. Bamboo activated carbon phisically adsorbed the CO2 of maximum 106 mg/g-A.C in the condition of 90% CO2 and adsorption temperature of 20 oC. The CO2 adsorption ability of bamboo activated carbon was not changed in the 5 cyclic test of desorption and adsorption. Key words: Bamboo, Activated Carbon, CO2 Activation Methol, CO2 Adsorption. 1.. C «. í, CO , ¤D Ù« À. «Ë ÍA O (g 5ûdÑ Âj2 D ñõ (g5ûd Ùétk³ _G CO Ùét (¤Í ñ ÍAÑ WGñ2 (O CO
