Reliable determination of element contents in heterogeneous waste fractions

Recently a particle based procedure has been developed to characterize chlorine content in heterogeneous waste fractions by sorting analysis and fractionated chemical analysis. The procedure generates reliable results including variances within a few hours. At the same time the development of mobile RFA analysis allows on-site analytical characterization. The combination of sorting analysis and RFA elemental characterization may offer the opportunity for an on-site multiple elements haracterization within a short period of time.
For testing those opportunities a RDF has been characterized not only by sorting but also by RFA analysis. The results show that the elements lead, cadmium, antimony,chromium and zinc are distributed extremely heterogeneous as known for the element chlorine. For every single element different 'levels of preferred concentrations� occur. Therefore the result of a chemical analysis is strongly depending on the number of high load contributors reaching the sample and their particle weight.
