Abstract

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 μg/g, 0.10 μg/g, 0.11 μg/g, and 0.08 μg/g, respectively. This method was successfully applied to the simultaneous determination of arsenic, bismuth, tellurium, and selenium in soil samples.

摘要

介绍了氢化物发生多道原子荧光光谱法（HG-MC-AFS）在土壤分析中的基本原理和应用。一般认为，常用的单道或双道 HG-AFS 一次只能同时检测一个或两个元素。在这项工作中，开发了一种新的方法，通过同时检测砷、铋、碲和硒，利用 HG-MC-AFS 对土壤样品进行分析。砷、铋、碲和硒的方法检出限分别为 0.19μg/g、0.10μg/g、0.11μg/g 和 0.08μg/g。该方法成功应用于土壤样品中砷、铋、碲和硒的同时测定。
