Simultaneous Quantitative Analysis of Arsenic, Bismuth, Selenium, and Tellurium in Soil Samples Using Multi-channel Hydride-Generation Atomic Fluorescence Spectrometry

The basic principles and the application of hydride-generation multi-channel atomic fluorescence spectrometry (HG-MC-AFS) in soil analysis are described. It is generally understood that only one or two elements can be simultaneously detected by commonly used one- or two-channel HG-AFS. In this work, a new sample-sensitive and effective method for the analysis of arsenic, bismuth, tellurium, and selenium in soil samples by simultaneous detection using HG-MC-AFS was developed. The method detection limits for arsenic, bismuth, tellurium, and selenium are 0.19 mu g/g, 0.10 mu g/g, 0.11 mu g/g, and 0.08 mu g/g, respectively. This method was successfully applied to the simultaneous determination of arsenic, bismuth, tellurium, and selenium in soil samples.
