| Abstract: | The sample of Pb - Ca alloy is dissolved in nitric acid and Na concentration in the sample is determinated directly by FAAS. The detective method is of good stability and accuracy, and is suitable to be used in the analysis of Na（0.01 ～0.3%） in Pb- Ca alloy. Its standard returns-ration varies from 98.0% to 103.5%. The relative standard deviation ranges between 0.10% and 0.18%. |
