Determination of arsenic, antimony, selenium, tellurium and bismuth in nickel metal by hydride generation atomic fluorescence spectrometry Original Research Article

A simple and rapid method is described for the determination of trace amounts of arsenic, antimony, selenium, tellurium and bismuth in nickel metal by hydride generation atomic fluorescence spectrometry (HGAFS). The five elements are coprecipitated simultaneously with lanthanum hydroxide and separated quantitatively from a nickel matrix and other interfering elements prior to the determination. The detection limits of arsenic, antimony, selenium, tellurium and bismuth in samples are 0.10, 0.15, 0.11, 0.10 and 0.45 μg g−1, respectively.
