Abstract
The adsorptive removal of tetrachloroethylene (perchloroethylene: PCE), one of the contaminants of groundwater, onto activated carbon fibers(ACFs) in liquid phase was experimentally examined.
The adsorption capacities of ACFs were larger than that of granular activated c arbon (GAC), and the adsorption isotherms of PCE onto ACFs and GAC were of Freundlich type.
The amounts of PCE adsorbed onto ACFs were inversely proportional to the specific surface area, the pore volume and the amount of water adsorbed, significantly.
In addition, the amount of PCE adsorbed on to ACF in liquid phase is rising with the ACF surface of being hydrophobic.
