Abstract: The xenon adsorption on different based activated carbon fibers(ACFs) and activated carbon fiber modified was studied. The results show that the xenon adsorption amounts of the ACFs are not increased with the increasing of specific surface area of the ACFs. The micropore size of the ACFs becomes narrow after the ACFs modification, meanwhile the xenon adsorption amounts of the ACFs increase a little. The structures of the AC.Fs do not change before and after the adsorption of xenon.

Key words: activated carbon fiber, adsorption property, xenon
