Kurzbeschreibung (Abstract)
A regular sample of real municipal solid waste (MSW) spiked with a '^Cn-OCDD standard has been pyrolysed in a model reactor. Dechlorination has occured and isomeric profiles are found for the homologue groups of tetra- to octachlorinated PCDD. A mass balance over the labelled carbon introduced by the '"^Cu-OCDD standard and emitted by the formed tetra- to octachlorinated '''C-- PCDD shows that 85% of the input "Cij-PCDD get through the pyrolysis without thermal decomposition. Decomposition rates and homologue patterns of native and labelled dioxins differ a lot due to different transit times in the oven. But the congener profiles of the labelled PCDD correspond with those ofthe native PCDD. This seems to indicate that the congener pattern determing step does not take place during pyrolysis but in the gas phase.
