| Abstract: | 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. |
