摘要
用原子吸收光谱法测定Mn、Zn、Cu金属元素的常规监测中,需频繁更换Mn灯、Zn灯和Cu灯等空心阴极灯,耗时费力,增加了时间成本。文章介绍了一种新方法,用Mn灯、Zn灯两种空心阴极灯可作为Cu灯空心阴极灯使用。在实际操作中减少了更换灯的频次和预热次数,使测试工作变得经济而省时,降低了监测成本,提高了工作效率,是一项值得推广的方法改进。
In the routine monitoring of Mn, Zn, Cu determination by atomic absorption spectrometry, the hollow - cathode lamp of Mn, Zn and Cu need to be replaced frequently, which took too much time. The article introduced the hollow - cathode lamp of Cu could be replaced by that of Mn and Zn. In practice the frequency of replacing the lamps and preheating will be reduced, which brings down the monitoring cost and promotes the work efficiency. This method improvement is worth popularizing.
