Determination of Trace Amount of Selenium and Tellurium in Geological Samples by Hydride Generation Nondispersive Atomic Fluorescence Spectrometry |
| |
| Abstract: | A hydride generation nondispersive atomic fluorescence spectrometric
method has been developed for determination of trace amount of Se and Te
in geological samples. Under the optimum conditions selected by the author,
the best attainable detection limits of Se and Te are both 0.3 ng. Ferric chl-
pride and thiourea are recommended as the reagents for eliminating interfer-
ences. The spectral interference from Bi reported in the literature can be
completely overcome by using Te EDL containing tellurium metal and tellurium
bromide. In ordinary samples, no seperation is required. |
