Methods for chemical analysis of zinc oxide produced by direct process―Part 5:Determination of manganese content―Flame atomic absorption spectrometry method
Methods for chemical analysis of zinc oxide produced by direct process -
Part 5: Determination of manganese content - Flame atomic absorption spectrometry method
1 Scope
This part of GB/T 4372 specifies the methods for determining the manganese content of zinc oxide produced by direct process.
This part is applicable to the determination of manganese content of zinc oxide produced by direct process, with the determination range of 0.0001%~0.0010%.
2 Method summary
Dissolve the specimen with nitric acid, use ferric hydroxide as co-precipitant to separate trace manganese from a large amount of zinc matrix to realize enrichment, measure the absorbance of manganese in the test solution with the atomic absorption spectrometer at a wavelength of 279.5nm, and then determine the manganese content by working curve method.
3 Reagents and materials
Unless otherwise specified, only the recognized analytical reagents and deionized water with a resistivity not less than 18.2MΩ shall be used during the analysis.
3.1 Ammonium persulfate.
