原子吸收石墨炉快速程序测定痕量金

Determination of Trace Gold by Electrothermal Atomic Absorption Spectrometry with a Rapid Furnace Programme

摘要: 制定了石墨炉快速测定Au的程序。通过快速干燥,省去灰化步骤或缩短灰化时间,使测定程序从常规法所需的79s缩短至18s(PE-3030)或25s(PE-603)。测定时间由2min降为1min,测定速度提高了一倍,并得到相似的准确度及精密度。

Abstract: A rapid furnace programme for determining trace Au by GFAAS is presented. Programme times can be reduced from 79s to 18s (PE-3030) and 25s (PE-603) through rapid drying and ashing or eliminating the ashing step. The determination speed increases by a fact
