Nickel-based alloy powder chemical analysis
Part 8. Determination of copper content
Neocuproine - chloroform extraction photometric
1 Scope
YS/T 539 This part specifies the method for determination of nickel-base alloy powder of copper content.
This section applies to the determination of nickel base alloy powder of copper content. Measuring range. 0.01% to 1%.
2 Method summary
The sample is dissolved by acid in the presence of citric acid, hydroxylamine hydrochloride to a reduction of the copper price in the range of pH 5 to 6, and neocuproine
Copper forming insoluble complexes, extracted with chloroform, the absorbance was measured in a spectrophotometer at a wavelength of 456nm.
