GB/T 6730.57-2004 Determination of chromium content in iron ore by flame atomic absorption spectroscopy (AAS). The iron ore sample is first processed to transfer the chromium element to the solution. The chromium atomization is performed with the help of the Flame atomization device, and the absorption degree of chromium atoms to specific wavelengths of light is determined by the light spectrum instrument. The chromium content in iron ore is accurately calculated by Absorbance according to the standard Linear dispersion. This standard provides a key technology for evaluating the mass of iron ore, which helps the steel industry to judge the characteristics of ore. It is widely used in iron ore mining, processing and steel smelting.
