CHARACTERIZATION OF ELECTRONIC WASTE MATERIALS BY INSTRUMENTAL NEUTRON ACTIVATION ANALYSIS FOR CERTIFIED REFERENCE MATERIAL PRODUCTION

Recycling of Waste from Electrical and Electronic Equipment provides an accessible source to gather Technology Critical Elements which are in constant need. The main metrological challenge consists in the lack of Certified Reference Materials for this kind of matrices impeding to perform SI traceable and reliable analytical measurements on those heterogeneous materials. This work describes the adoption of relative- and k0-standardization of Instrumental Neutron Activation Analysis to quantify some of the Technology Critical Elements for certification in two Reference Material candidates.
