火焰原子吸收光谱法测定锡阳极泥中铋的含量

Determination of Bismuth Elements in Tin Anode Slime by Flame Atomic Absorption Spectrometry

本文建立了火焰原子吸收光谱法测定锡阳极泥中含量在1%~5%铋元素的分析方法,研究了样品的溶解方式、酸度、干扰元素对铋含量测定的影响。试验结果表明,该方法铋的检出限为0.30μg/mL,回收率为96.8%~105.0%,相对标准偏差为0.51%~1.70%,该方法能够实现准确测定,精密度和回收率都较好,能够很好地应用于锡阳极泥中铋元素的分析检测。

In this paper,an analytical method for the determination of bismuth in tin anode mud by flame atomic absorption spectrometry was established,and the influence of the dissolution method,acidity and interfering elements of the sample on the determination of bismuth was studied.The test results show that the detection limit of this method is 0.30μg/mL,the recovery rate is 96.8%~105.0%,and the relative standard deviation is 0.51%~1.70%,this method can achieve accurate determination,with good precision and recovery rate,and can be well applied to the analysis and detection of bismuth in tin anode mud.
