摘要：

The effectiveness of glucose as a chemical modifier for the determination of Sb and Se by electrothermal atomic absorption spectrometry has been evaluated. The effect of increasing glucose concentration on the thermal behaviour of both elements and on the graphite tube surface is described. Glucose allows the quantitative stabilization of Sb and Se up to 1300 degrees C compared with 700 degrees C without glucose. Furthermore, this chemical modifier significantly reduces interference by phosphorous in the determination of Se and by chloride in the determination of Sb.
