1 Scope
This section GB/T 8151 specifies the method for determination of nickel content in zinc concentrates.
This section applies to the determination of nickel content of zinc concentrates. Measurement range. 0.0030% to 0.050%.
2 Method summary
Samples with hydrochloric acid, nitric acid, sulfuric acid dissolved in ammonium citrate solution, and extracted with chloroform nickel dimethylglyoxime complexes generated with the
Zinc, iron and other elements separated. In hydrochloric acid medium, atomic absorption spectrometer at a wavelength of 232.0nm, air - acetylene flame measured absorption of nickel
Luminosity.
