| 摘 要： | 石墨炉原子吸收光谱法(GFAAS)绝对分析近年来得到了较显著的发展,其主要原因是由于GFAAS中基体干扰问题获得了解决;用以描述GFAAS性能的特征质量MOE值相对稳定;以及用L’vov提出的计算MOT值的式子算出的32个元素的MOT值已比较接近其实验MOE值。大量数据表明完全有可能实现GFAAS绝对分析。

| Abstract: | A review is given of major advances in absolute analysis by graphite furnace absorptionspectrometry. Three main problems, namely, elimination of matrix interferences, stabilization ofcalibration in time and ensuring identical calibration among similar instruments and theoreticalcalculation of characteristic masses, m_0 based on L'vov's model have been relatively solved.Results have shown that there is a good correlation between calculated and experimentallyobtained m_0. |
