| Abstract: | The silicon contents in aluminum alloy of battery case of satellite systems can be measured by N 2O-C 2H 2 atom absorbing spectrum method. The selection of measuring conditions such as burner height, combustion supporting ratio and resonance line and the effect of acidity, temperature and N 2O-C 2H 2 flame area on measuring precision are discussed. The practical application shows that the method has the advantages of high sensitivity, small interference, good selectivity and repeatability, and simple in operation, easy to master and short cycle of analysis, the precision and accuracy meet the needs of the development of battery cases of satellite systems. |
