title: [Determination of trace selenium and tellurium in steel by hydride-generation nondispersive atomic fluorescence spectrometry].
abstract: A method was developed for the determination of trace Se and Te in steel by ion-exchange-separation hydride-generation nondispersive atomic fluorescence spectrometry. 40% (V/V) chlorhydric acid was selected as the best medium for hydride reaction. The detection limits of Se and Te are 0.27 and 0.33 ng/mL, relative standard deviations are 6.99 and 6.11%, respectively. The recovery was in the range of 96.7-102.0%. The results are satisfactory.
