摘要
采用原子吸收光谱法测定样品中铋含量。考虑到铋的质量分数对测定的影响,控制铋含量;采用火试金法能够实现铅铋合金阳极中金、银含量连续测定。该方法测定结果稳定可靠,准确度高,精密度良好,金的回收率可达到99﹪,银回收率可达到97﹪,能够很好的做到铅铋合金阳极中金、银含量的测定。
The content of bismuth in samples was determined by atomic absorption spectrometry.Considering the influence of bismuth content on determination,bismuth content is controlled.Continuous determination of gold and silver content in lead-bismuth alloy anode can be realized by fire assay.The method has the advantages of stable and reliable determination results,high accuracy and good precision,the gold recovery rate can reach 99%,and the silver recovery rate can reach 97%,and the method can well measure the gold and silver content in the lead-bismuth alloy anode.
