用KOH对市售的粉末活性炭进行表面改性。采用BET分析改性前后活性炭的表面结构，并采用活性炭涂层电极构建电容去离子吸附装置，研究改性后电极的去离子效果。研究表明：经过KOH改性后，活性炭的比表面积从519．25 m2/g增加到975．07 m2/g，提高了87．78%，中孔孔容占总孔孔容的百分比提高了48．28%，改性后活性炭的孔隙结构和孔径的分布更有利于溶液中的Na+和Cl-通过，提高了电极的吸附速率。

The surface modification has been made to the commercial activated carbon powder with KOH. The sur-face structure of activated carbon,before and after the modification are analyzed with BET. The capacitive deioniza-tion adsorption device is established with activated carbon-coated electrodes. The deionization effect of the modified electrode is researched. The research shows that after being modified with KOH ,the specific surface area of activa-ted carbons is increased from 519.25 m2/g to 975.07 m2/g;it means that its increase in percentage is 87.78%. The percentage of medium-size pore volume is 48.28%higher than the total pore volume. The pore structure and pore-size distribution are more advantageous for Na+and Cl-to get through,raising the electrode adsorption rate.
