火焰原子吸收光谱法测定粗铅中铁量

Determination of Iron In Crude Lead by Flame Atomic Absorption Analysis

介绍了粗铅中铁的火焰原子吸收光谱分析方法,确立了火焰原子吸收分析铁的仪器条件。通过对其共存干扰离子的影响及其准确度和精密度测试,表明在5%的硝酸介质中使用空气-乙炔火焰原子吸收测定,方法准确、快速、结果可靠,测定范围0 05%～2%。

Flame atomic absorption spectrum(FAAS)analysis for iron in crude lead has been studied,and established the instrument condition of FAAS determination for iron.After the test of coexist interfere ion,accurateness,precision.It shows that the method is simple?speedy,sensitive in HNO3(5%) solution.The range of determination is 005%～2%.
