ResumoThe simultaneous determination of six metal ions (Cu2+, Zn2+, Ni2+, Mn2+, Co2+, Pb2+) by using dynamic ion-exchange chromatography is proposed. The method was applied to the analysis of human hair after HNO3HClO4 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.
