Abstract
A number of native polychlorinated Dibenzo-p-dioxins (PCDD) and Dibenzofurans (PCDF) were
isolated from the fly-ash of a municipal waste incinerator by soxhlet extraction.
Spectroscopic analysis of seven PCDD`s and ten PCDF`s by GC/MS analysis coupled with
FTIR-spectroscopy was performed. For vibrational assignment of vibrations some representative
IR spectra were simulated by ab initio calculations at the Hartree Fock level with the basis set 3-21 G (d,p).
The utility of GC/FTIR/MS spectroscopy for congener analysis and isomer discrimination in native
dioxin samples is discussed.
