摘要
对火焰原子吸收光谱法测定水泥中的钠、钾、镁和铁的方法进行研究。在选定的最佳仪器条件下,测定钠、钾、镁和铁的RSD分别为1.81%、1.05%、2.68%、1.12%。水泥样品中钠、钾、镁和铁的回收率分别为102.0%—104.0%、98.4%—100.4、98.0%—102.0%、98.0%—100.3%。方法操作简单,测试快速,结果准确稳定。
The method for the determination of sodium,potassium,magnesium and iron in cement by atomic absorption spectrometry（AAS） was studied.Under the optimum experimental conditions,the RSDs of sodium,potassium,magnesium and iron were respectively 1.81%,1.05%,2.68% and 1.12%.The recoveries of sodium,potassium,magnesium and iron were respectively 102.0%—104.0% and 98.4%—100.4%,98.0%—102.0% and 98.0%—100.3%.The method has simple operation and rapid determination with accurate and stable results.
