GB/T 4325.20-2013 《Methods for chemical analysis of molybdenum - Part 20: Determination of manganese content - Flame atomic absorption spectrometry》 Related products

This standard specifies a method for the determination of manganese content in molybdenum powder, molybdenum bar, molybdenum trioxide and ammonium molybdate by flame atomic absorption spectroscopy (AAS), with a determination range of 0.0002% to 0.100%. Absorbance of manganese in dilute nitric acid or muriatic acid medium after the sample has been analyzed for hydrogen oxidation, nitric acid or muriatic acid. This standard provides a reliable technical basis for the analysis of manganese content in molybdenum materials and is suitable for mass detection and control.
