This standard specifies a method for the determination of lithium content in aluminum and aluminum alloys by flame atomic absorption spectroscopy (AAS), which is applicable in the range of 0.0020% to 12.00%. After the sample is dissolved by muriatic acid, hydrogen peroxide and nitric acid, the measurement Absorbance at a wavelength of 670.8 nm is used to calculate the lithium content. This method provides a reliable technical means for the accurate determination of lithium in aluminum alloys.
