Abstract

Non-dispersive atomic fluorescence spectrometry is used to determine trace amounts of nickel. A non-dispersive system employing a laboratory-made graphite furnace atomizer and a high frequency discharge lamp with a hollow electrode is used.The detection limit of nickel is 0.01 ng. The linear dynamic range covers about three orders of magnitude in concentration. Interference studies are made with respect to fifteen elements and three acids. The method is successfully applied to the determination of nickel in iron and steel.
