本文叙述了关于人发中铊快速测定的一种原子吸收分光光度操作方法。将500微克样品溶在硝酸中并用过氧化氢处理,然后进样10微升在石墨炉中进行电热原子化分析。本法的检出浓度是1mg Tl/kg,该方法适用于法庭调查。添加32mgTl/kg的发样的一系列峰高的相对标准差是3％。 This article describes an atomic absorption spectrophotometric method for the rapid determination of thallium in human hair. Five hundred micrograms of sample was dissolved in nitric acid and treated with hydrogen peroxide, and 10 microliters of an injection was then subjected to electrothermal atomic analysis in a graphite furnace. The detection concentration of this method is 1mg Tl / kg, the method is suitable for forensic investigations. The relative standard deviation for a series of peak heights added with a 32 mg Tl / kg sample was 3%.
