GB/T 6730.75-2017 《Iron ores—Determination of sodium content—Flame atomic absorption spectrometric method》 Related products

GB/T 6730.75-2017 specifies the method for the determination of sodium content in iron ore by flame atomic absorption spectroscopy (AAS). The standard applies to natural iron ore, iron concentrate, sinter and pellet, and the determination range (mass fraction) is 0.005% -2.00%. The standard specifies the required reagents, instruments and equipment, and standardizes the preparation and analysis steps of the sample. It provides a unified and reliable operation method for the accurate determination of sodium content in iron ore, and helps to control the mass of iron ore and related research.
