| Abstract: | Si and Mg content in aluminum alloy were determined by spectrophotometry. The experimental conditions, such as choice of the acidity and reagents dosage of developer, control of developing reaction condition, stability of colored complex compound, were discussed. The results showed that accuracy and precision of the method could meet the requirement of determination of Si and Mg content in aluminum alloy in production, and the experimental conditions could be easily controlled. The method is suitable for use to determine Si and Mg content in aluminum alloy. |
