Determination of zinc in blood serum and red cells by atomic absorption spectrometry

Abstract

Conditions for the atomic absorption spectrometric determination of zinc in blood serum and red cells were examined. Both serum and cell samples must be preliminarily deproteinized since those by simple dilution gave unstable flame. The recoverises of zinc by this procedure were 99% for serum and 96% for cells. Distributions of zinc concentration in serum and red cells of 50 patients were: 81100 μg/100 ml for serum and 12011400 μg/100 ml for red cells. The limiting concentration fot the determination was 0.02 ppm as giving 0.1% absorptivity.
