Abstract

Furnace atomic absorption has been coupled with an automatic sample dispenser and used for the analysis of lead and cadmium in a nitric acid-blood mixture. Relative standard deviations of 2–5% for lead and 3–6% for cadmium have been measured using 2-µl sample volumes. The accuracy of the method has been established by a chelation and solvent extraction technique followed by flame AA analysis.
