In selenium determination by carbon-furnace atomic absorption spectrometry, organic materials severely decrease selenium sensitivity. In order to remove the severe negative interference due to organic materials, matrix modifications by addition of Pd, Pt, Ni and Rh were compared. Palladium was found to be most effective. Addition of 100μg ml-1 Pd completely removes the negative interference due to up to 1.5% albumin and restores the sensitivity to that of a simple inorganic Se(IV) solution without organic materials.
