Trace Element Analysis for Different Samples of Bread in Sudan Using X-Ray Fluorescence Spectrometry

Abstract

This work deals with applying X-ray fluorescence spectrometry to detect trace elements in bread samples. The intensities of the lines of these trace elements, as a function of concentration, were measured to establish the sensitivity of the spectrometer. The result obtained that the two peak energies found 3.31 KeV and 13.47 KeV are energies of the Kα peak of K2O and Br respectively. The results obtained that the highest element and compound concentrations in all samples are Nb (11.05–1971.97) ppm and K2O (6.5–51.932) ppm respectively, while the least element and compound concentrations in all samples are Zr (0.34–934.0) ppm and MnO (1.10–14.790) ppm, respectively.
