In this research, the main effects of regeneration time, regeneration temperature and microwave power on adsorption properties of activated carbon were investigated. The optimal conditions have been identified to be the regeneration heating time of 10min, regeneration temperature of 702°C and microwave power of 400W. Under above conditions, iodine adsorption number and yield of activated carbon are 1,150mg/g and 78.25%, respectively. Furthermore, the activated carbon was characterized by nitrogen adsorption isotherms at 77K, and the porous structures were analyzed by BET. The BET surface area is 1,033m2/g. Non local density function theory was used to characterize total pore volume, which is 1.28ml/g. The activated carbon was characterized by FTIR and SEM. The results of SEM indicated that impurities which covered the surface of activated carbon are cleaned. It can be seen from FTIR analysis that functional groups of activated carbon are changed through microwave heating.
