Determination of Lead in Ferrosilicon by Sequential Injection Hydride Generation Atomic Fluorescence Specttrometry

A method of injection hydride generation combined with atomic fluorescence spectrometry for the determination of Pb in ferrosilicon was reported in this paper.The sample was digested with HNO3-HF-HClO4.Under the selected condi-tions,recovery of the method was in range of 95%～106%,detection limit was 0.410 3 ng/mL and RSD was 1%～5%.
