Abstract
The sample solution containing chromium was vaporized and atomized from a tantalum filament by electrical heating into an argon stream within an absorption chamber. The interference of various metals on the atomic absorption spectrometry of chromium was investigated. Interferences were minimized by using a high filament temperature. The flameless atomizer was used for the determination of chromium in steel at a filament temperature of 2150°; with the steels investigated no matrix effect was observed, and the accuracy and precision were satisfactory.
