Abstract

ICP atomic fluorescence spectrometry has been used to analyze a variety of materials that include an iron ore and a blast furnace slag, as well as low alloy and stainless steels. The technique provides selectable simultaneous multielement analysis with good detection limits. Spectral interferences and background effects are generally avoided and no computer, monochromator, polychromator, or complex scanning mechanisms are required. An examination of the effect of an iron matrix on detection limits shows a small but measurable degradation for aluminum and chromium. The intensity-concentration relationship exhibits strict linearity over three to four orders of magnitude measured from the lowest determinable concentration. The analytical results for aluminum, cobalt, chromium, copper, manganese, molybdenum, nickel, and silicon are in good agreement with certified values.
