Abstract
The simultaneous determination of six metal ions (Cu 2+, Zn 2+, Ni 2+, Mn 2+, Co 2+, Pb 2+) by using dynamic ion-exchange chromatography is proposed. The method was applied to the analysis of human hair after HNO 3HClO 4 digestion, with detection limits of ca. 1 μg g −1 for all the metals examined, using Co as an internal standard. The quantitative data were confirmed by analysing the same hair samples by atomic absorption spectrometry and x-ray fluorescence spectrometry.
