Methods for chemical analysis of bismuth Determination of copper content
Double acetaldehyde oxalyl Spectrophotometric Method
1 Scope
This section provides the determination of copper content of bismuth.
This section applies to the determination of bismuth in copper content. Measurement range (mass fraction). 0.0002% to 0.004%.
2 Method summary
Sample decomposition by nitric acid. In pH8 ~ pH10 ammonia medium, in order to mask body bismuth ammonium citrate, oxalic acid bis double acetaldehyde hydrazone (by the bicyclic
The oxalic acid bis cyclohexanone and acetaldehyde hydrazone reaction) with copper to form a stable purple complex in a spectrophotometer at 540nm wavelength absorption measured
Luminosity.
3 Reagents
3.1 commercially available reagents
3.1.1 ammonia (ρ0.90g/mL).
3.1.2 acetaldehyde solution (40%).
3.2 solution
