Direct determination of beryllium, cadmium, mercury, lead and thallium in whole blood by Zeeman modulation polarization spectrometry

Abstract

A methodic approach for determination of beryllium, cadmium, mercury, lead and thallium in whole blood without preliminary sample digestion based on Zeeman modulation polarization spectrometry has been proposed. Using of this type of selective atomic absorption spectrometry simultaneously with individual optimization of surface and matrix modification, furnace programs and sample dilution allowed coping effectively for both spectral and matrix-based interferences.
