| Abstract: | Flameless atomic absorption spectrometry of antimony has been investigated with a carbon rod device. Antimony may be determined in solution at a level of 10-10 g with a sample volume of 0.5 μl. Optimal conditions and interferences are described. Matrix effects on antimony necessitated a preliminary solvent extraction of the chloride complex from hydrochloric acid solution containing nitrite with methyl isobutyl ketone. The determination of antimony in metallurgical samples was shown to be satisfactory. |
