本文研究制定了一种泡沫塑料吸附-石墨炉原子吸收光谱法测定地质物料中痕量铊的分析方法．在所定的实验条件下，方法检出限为0．05μg／g，校准曲线范围为10－300ng／mL；T1含量水平为0.71μg／g时的测定精度（RSD，n=11）为6.0％，方法回收率99．0％－100.0％。经标样及大量样品分析验证，分析方法准确可靠。
In this paper, a method for the determination of trace thallium in geological materials by foam plastic adsorption-graphite furnace atomic absorption spectrometry was developed. Under the experimental conditions, the detection limit was 0.05μg / g and the calibration curve ranged from 10 to 300ng / mL. The determination accuracy (RSD, n = 11) was 6.0% at the level of 0.71μg / , Method recovery 99.0% -100.0%. The standard sample and a large number of sample analysis and verification, accurate and reliable analytical methods.
