Abstract

This project shows an analytical proposition combining Thermospray flame furnace atomic absorption spectrometry (TS-FF-AAS) and sequential determinations. In this way two factors can be combined: high sensitivity (TS-FF-AAS) and analytical frequency (sequential determinations). In addition, some procedures will be used to improve precision and accuracy in the determination of As, Cd, Co, Cr, Cu, Mn, Ni, Pb and Zn. The first factor in the internal standard in AAS, this procedure is only possible in equipments with sequential determinations. The second will be the use of chemometrics resources to study concomitants and variables in TS-FF-AAS. Finally, with this project it will be possible to develop fast analytical methods to amplify the resolution of several analytical problems in food and environmental analyses. This project shows interesting alternatives that can be positive in the analytical community. (AU)
