Determination of Trace Nickel in Human Hair by Graphite Probe Furnace Atomic Absorption Spectrometry

    Abstract
  • A simple, ralid and accurate method for the determination of trace nickel in human hair samples by graphite probe furnace AAS has developed. The concentration of nickel and the absorbance (Peak-area mode) showed an excellent linear relation in the range of 0～200ng/mL. The characteristic mass, detection limit and precision of nickel were 51.83pg, 86.82pg and 3.86% RSD respectively. A standard addition test gave a recovery of 94.5～105.7%.
