GB/T 20975.33-2020 《Methods for chemical analysis of aluminium and aluminium alloys—Part 33：Determination of potassium content—Flame atomic absorption spectrometric method》 Related products
This standard specifies the method for the determination of potassium content in aluminum and aluminum alloys by flame atomic absorption spectroscopy (AAS), which is suitable for arbitration determination of potassium content in the range of 0.0010% to 1.00%. The standard describes the analytical process of dissolving samples with muriatic acid and hydrogen peroxide, adding potassium chloride as an ionization inhibitor, and measuring potassium Absorbance at specific wavelengths, providing a technical basis for the accurate determination of potassium content in aluminum and aluminum alloys.
