本文中提出了石墨炉原子吸收法快速测定钢铁中微量铬的方法。该法采取缩短干燥时间和取消灰化阶段,每次可缩短测定时间48秒,但不损失测定的精密度或准确度。
In this paper, graphite furnace atomic absorption spectrometry rapid determination of trace chromium in steel. The method takes a shortened drying time and a deassertion phase, each reducing the measurement time by 48 seconds without sacrificing the precision or accuracy of the assay.
