| Abstract: | The amount of calcium in the silicon calcium alloy was determined by nitrous oxideacetylene flame atomic absorption spectrometer. The optimum conditions were studied. The method has the advantages of high sensitivity, less interference and good in selectivity and reappearance. The relative standard deviations are all less than 1. 0%(n = 6)with standard adding recovery of 97. 0%-100. 0%, which are satisfactory for quality of laboratory. |
