火焰原子吸收光谱法测定再生锌原料中的铁

Determination of Iron in Regenerated Zinc Materials by Flame Atomic Absorption Spectrometry

将含铁再生锌原料试样用王水溶解、过滤定容后,在稀盐酸介质中,用火焰原子吸收光谱法测定铁含量。考察了试样消解方法、酸介质、试液酸度和共存元素对铁测定结果的影响。结果表明,此方法测定结果准确可靠,操作简便,稳定性好,精密度高,回收率在99.05%~107.9%,适用于再生锌原料0.01%~5%铁质量分数的测定。

The sample was dissolved with aqua regia,then diluted to the volume after filtrated.In dilute hydrochloric acid medium,the iron in the sample was determined by flame atomic absorption spectrometry.The influence of dissolution method,acid medium,acidity and coexisting elements on determination were discussed.The results show that the method is accurate,reliable,easy for operation,stable,and has high accuracy and recovery rate of 99.05%-107.9%.This method is suitable for determining of 0.01%-5%iron in regenerated zinc materials.
