Abstract:In this article, a methodology for the wavelength dispersive X-ray fluorescence analysis of corrosion residues is described. Corrosion residues are generally composed of elements that are, total or partially, in a reduced state. Therefore, to prepare fused beads to be measured by wavelength dispersive X-ray fluorescence, it is necessary to oxidize species and to avoid any analyte loss, as sulfur, which is present in residues composition.The combination of an oxidizing agent (LiNO 3 ) and a flux (Li 2 B 4 O 7 +… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
