Abstract

By simultaneously recording X-ray fluorescence intensities and X-ray diffraction pattern at a microscopic level highly heterogeneous samples of fly-ash particles have been analyzed. From the data achieved by this combined experiment, the main minerals in the particles have been identified and the size distributions of these minerals have also been determined. The distribution of heavy elements, recorded from their fluorescent intensity, is presented and the impact of sample surface topology and anomalous attenuation is discussed. Estimates of the concentration of the these heavy elements are given and correlation analysis has been performed indicating that most of these elements seem to appear at the surface of the fly-ash particles.
