Resumen

In this paper a method for determining germanium by hydride generation-uv-visible molecular absorption spectrometry with diode-array detection is described. The molecular absorption maximum of germanium hydride appears to be outside the instrumental possibilities of the spectrophotometer and for this reason the determination is performed at 190 nm. Hydride generation and determination procedures are optimized and a linear response up to 200 μg is obtained. The method is used to determine germanium in an organogermanium compound. The sample is first halogenated and germanium is then extracted into NaOH aqueous solution. © 1990.
