PIXE Analytical Method Applied in the Study of Environmental Samples Used as Bioindicators

摘要

In this study we apply Proton Induced X-Ray Emission (PIXE) spectrometry to determine the heavy metal content of some environmental certified reference materials and moss samples. The PIXE experiments were performed using a proton beam provided by the 3 MV TandetronTM particle accelerator from the National Institute for R&D in Physics and Nuclear Engineering Horia Hulubei (IFIN-HH) in Magurele-Bucharest. The trace elements in mosses pellets and certified standard samples were measured. The elements identified were: Al, P, K, Ca, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn and As, and quantitatively determined were: K, Ca, Ti, V, Cr, Mn, Fe, Ni, Cu and Zn. The concentrations values of heavy metals in the analyzed samples determined by PIXE technique were compared with the results obtained by Flame Atomic Absorption Spectrometry (FAAS) method.
