GB/T 6609.19-2004 Determination of lithium oxide content in aluminum oxide by flame atomic absorption spectroscopy (AAS). The aluminum oxide sample is first processed to convert the lithium oxide into lithium ions in the solution. The lithium atomization is made by using a Flame atomization device, and the absorption degree of lithium atoms to specific wavelengths of light is measured by means of a light spectrum instrument, that is, Absorbance. The lithium oxide content in aluminum oxide is accurately calculated according to Absorbance through the standard Linear dispersion. This standard provides an effective means for aluminum oxide mass detection and helps to accurately evaluate the purity of aluminum oxide products. It is widely used in aluminum oxide production and related industries.
