近几年来,我国已有人对石墨炉平台技术进行评价并在实际分析中开始将平台技术加以应用。如应用石墨炉平台技术测定金属铅中的微量铊。有关平台技术国外有不少报导。如:Kaiser等人研究了在石墨炉中加上Lvov平台和基体缓冲剂分析自来水和合成水中的铅、镉等元素,认为可以大大减少基体的干扰。本文应用170—70型塞曼效应原子吸收分光光度计,在石墨炉中加上热解平台,对测定矿山污水中微量铜进行了探讨性的研究。实验证
In recent years, some people in our country have evaluated the graphite furnace platform technology and started to apply the platform technology in practical analysis. Such as the application of graphite furnace platform technology to determine trace amounts of metallic thallium. There are many reports about platform technology abroad. For example, Kaiser et al. Studied the analysis of lead, cadmium and other elements in tap water and synthetic water by adding Lvov platform and matrix buffer in a graphite furnace, and considered that the interference of the matrix can be greatly reduced. In this paper, 170-70-type Zeeman effect atomic absorption spectrophotometer, coupled with the pyrolysis furnace platform, for the determination of trace amounts of copper in mine effluent were discussed.
