Abstract
Extraction experiments with spiking of C-13(12)-PCDD/Fs were performed with a variety of PCDD/Fs contaminated samples. The extraction recove ry of PCDD/Fs was mainly influenced by PCDD/Fs concentration and the s ample matrix. Generally, the first soxhlet extraction with toluene has suitable recovery. From the selected samples, only FAMS4 and 5 which are fly ashes with high concentration, the recovery of the first soxhl et extraction with 24 hr. is low, but PCDD/Fs were almost completely r emoved after 72 hr.
