| Abstract: | The measurement of copper and iron trace content in the mixture zine powder by using the air-C2H2 flame atomic-absorption spectroscopy was studied synthetically considering measuring conditions and disturbing factors.The method possesses many advantages such as high sensitivity and accuracy, less interference and good repeatability and selectivity.The deviation RSD<2.0% (n=10)comparing to standard value.The standard adding recovery is in the range of 97.00%~102.00%(n=5).The use of the method fully suited to the control of copper and iron trace content in the mixture zine powder and the analysis for sample system has obtained good effect in practice. |
