Trace amounts of antimony, germanium and tin in high-purity iron were quantitatively separated by a reductive coprecipitation technique with palladium, and determined by electrothermal atomic absorption spectrometry. When sodium phosphinate (NaPH2O2) was used as a reductant, antimony and germanium could be separated simultaneously from large amounts of iron. Similarly, when sodium tetrahydroborate (NaBH4) was used, germanium and tin could also be separated simultaneously. The atomic absorbances of antimony, germanium and tin were increased by about 1.5, 3.7 and 4.5 times, respectively, in the presence of palladium. The limits of detection (corresponding to three times the standard deviation of the blank) of antimony, germanium and tin were 0.019, 0.010 and 0.031 μg g-1, respectively.
