摘要
研究了一种采用火焰原子吸收光谱法测定硫酸钡中微量钠元素的新方法。此方法具有简单快速、准确度高和精密度好等特点。实际样品中的钠元素平行测定六次,其结果的相对标准偏差是0.61%。所得加标回收率在96.5%~102.9%之间,进一步说明该方法具有一定的可靠性。
In the paper, a new method based on flame atomic absorption spectrometry was applied to the trace sodium determination in barium sulfate. This method was simple, fast , good accuracy and acceptable precision. The sodium concentration of sample was measured six times in the similar procedure, and the relative standard deviation was 0. 61%. The recovery was ranged from96.5 % to 102.9%.
