Improved determination of cadmium in blood by flame atomic fluorescence spectrometry

Abstract

A procedure is described for the determination of normal levels of cadmium in whole blood using flame atomic fluorescence spectrometry. This method represents an advance on previous work in that better control of the electrodeless discharge lamp source temperature has facilitated greater stability and thus better detection limits. Furthermore, sample pre-treatment by deproteinisation reduces the dilution factor from 1 + 4 to 1 + 1 so that the whole blood detection limit is improved to twice that of aqueous solutions.
