Abstract
AbstractDirect determination of selenium in human whole blood is carried out using graphite furnace atomization absorption spectrometry. Interferences of inorganic ions, especially iron, are eliminated by using a molybdenum coated furnace and a L'vov platform. Different oxydation states of selenium revealed the same results. By comparison with hydride generation atomic absorption spectrometry and fluorimetry after wet acid digestion it can be concluded that the described procedure resulted in accurate values for selenium concentrations in small volumes of human whole blood.
