Abstract：A commercial activated carbon(AC) was treated by an ultrasonic after being impreg-nated in a solution of potassium carbonate and an auxiliary agent. The impregnated activated carbon was reactivated, acid-washed and water-washed. The iodine number (I_2 number), methylene blue(MB) and nitrogen adsorption/desorption isotherms were measured. The re-sults show that the additive is in favour of increasing the I_2 number, MB and mesoporous ratio. Compared with general impregnating, the adsorption performance and the mesoporous ratio of AC treated by an ultrasonic were enhanced. With the increasing of ultrasonic power and time, the I_2 number, MB and mesoporous ratio were reduced. When the ultrasonic power is 40 W, the ultrasonic treat time is 50 min, the adsorption performance and mesoporous ratio are the best.
