Estudo técnico-econômico em fluorescência de raios-x por dispersão de ondas para comparação de metodologias de análise

Abstract

There is a lack of studies that addresses not only a technical part of an object of analysis, in industrial or laboratory process, but also the economic side. Current science values multidisciplinary studies with a high degree of specialization. The technical studies of fluorescence of rays-X dispersion of waves (FRXDO). With this problematic, this work had as objective the systematic analysis, the X-ray fluorescence, the escape of the samples with greater reliability and efficiency. Seven FRXDO analysis methodologies focused on a standard powder sample were used: Rigaku Filter, Qualy Filter, Capped Film, Porous Film, 4 and 5 gram Boric Acid Paste and Wax Paste. With a technical-economic analysis, it was possible to find the most reliable method from the technical point of view for the porous film, being also a methodology of more affordable price of preparation. It concludes that the work is not only a preliminary study of a focus on the methodologies in FRXDO, but also an idea of being done in future work, providing a legacy to the academic community.
