AB The incineration of Municipal Solid Wastes generates toxic products like fly ashes containing heavy metals and organochlorinated compounds. The presence of these materials in the fly ashes makes their treatment and valorization very difficult. In this work we present a process for the real time desorption and concentration measurement of chlorinated compounds and heavy metals. To this end a radio frequency (13.56 MHz) low pressure plasma (<500 Pa) process has been developed. The chemical analysis of exhaust gases for the identification of chlorinated compounds has been performed by on-line mass spectrometry. The heavy metals have been identified by optical emission spectroscopy. This study cleary shows that the low pressure plasma enhances the desorption of chlorine compounds. Furthermore, the hydrogen addition leads to a decrease of the reactive chlorine species and simultaneously, an increase of HCl.
