火焰原子吸收光谱法测定银粉中的铋

Determination of Bismuth in Silver Powder by Flame Atomic Absorption Spectrometry

提出了火焰原子吸收光谱法测定银产品中杂质铋的一种新方法。该方法利用氢氧化铁富集杂质铋,使铋与大量银分离后用原子吸收光谱法进行测定。所拟方法快速、简便、准确。可满足银产品生产的快速监控分析。

A new method for determination of the bismuth in silver powder by flame atomic absorption spectrometry is presented in this paper. The impurity of bismuth is gathered by iron hydroxide and separated with silver, and then determined by atomic absorption spectrometry. This method is rapid, simple, convenient and accurate, and can meet the requirement of rapid monitoring and analysis in production of silver products.
