Abstract
The influence of Pd, Pt, Rh, and Ir on the behavior of selenium in a g raphite furnace during the determination by electrothermal atomic abso rption spectrometry is studied. It is demonstrated that the loss of se lenium at the pyrolysis stage is proportional to the melting temperatu re of the platinum-group metal employed as the chemical modifier.
