GB/T 8704.9-2009 Ferrovanadium—Determination of manganese content—The potassium periodate oxidation photometric method and flame atomic absorption spectrometric method
Abstract
This part of GB/T 8704 specifies the determination of manganese content in vanadium iron by the potassium iodate photometry method and the flame atomic absorption spectrometry method. This part is applicable to the determination of manganese content in vanadium iron. The determination range (mass fraction) of the potassium iodate photometry method is 0.05% to 0.60%; the determination range (mass fraction) of the flame atomic absorption spectrometry method is 0.10% to 1.00%.
