In this study, an analytical method for perfluorinated compounds (PFCs) in granular activated carbon (GAC) was investigated. The investigation of analysis was conducted by using GAC which adsorbed PFCs from artificial waste water containing PFCs of known amount. As results, it was confirmed that Accelerated solvent extraction (ASE) method using acetone as the solvent was appropriate for the extraction of PFCs in GAC.
PFCs in used GAC samples, regenerated GAC samples, and a new GAC sample were analyzed by using the investigated method. The concentration of PFCs in the regenerated GAC was decreased by more than 99.9% compared with the used one. PFCs in GAC may transform and/or desorb at regeneration processes.
