โœฆ Synopsis

The simultaneous determmatlon of SIX metal ions (Cu*', Zn'+, N?+, Mn'+, Co'+, Pb") by usmg dynamic Ion-exchange chromatography IS proposed The method was apphed to the analysis of human hair after HNO,-HClO, digestion, with detectlon hnuts of ca 1 pg g -' for all the metals exammed, usmg Co as an Internal standard The quantltatlve data were confirmed by analysmg the same hair samples by atonuc absorption spectrometxy and x-ray fluorescence spectrometIy
