Abstract

In this study, two methods were developed for the sequential determination of As and Sb, Bi and Pb using fast sequential continuous flow hydride generation atomic absorption spectrometry. Limits of detection obtained for As and Sb were 0.15 and 0.16 μg L−1 and for Bi and Pb were 0.60 and 0.77 μg L−1, respectively. Arsenic, Sb, and Bi were free from the influence of possible interferents in the levels investigated, but Pb showed a significant analytical signal decrease when Co, Cu, Fe, Ni, and HNO3 were presented in the solutions. The methods were applied to the analysis of water from the Tietê River (São Paulo State, Brazil), sea water from Praia Grande—Ubatuba (São Paulo State), chicken feed, trace elements in water (NIST 1643e), and trace metals in drinking water (HPS TMDW). The obtained recoveries varied from 88 (for As) to 116 % (for Bi).
