Determination of indium and thallium by hydride generation and atomic-absorption spectrometry.
Hydride generation coupled with atomic-absorption spectrometry was applied to the determination of indium and thallium. The hydrides were generated in 1M HCl (In) and 1-1.5M HCl or HNO(3) (Tl) with 1% NaBH(4) solution, and were flushed with argon into an electrically heated silica tube. The characteristic mass for indium and thallium were 0.13 and 0.12 mug, respectively.
