GB/T 22661.7-2008 《Chemical analysis methods of potassium fluoborade - Part 7: Determiantion of sodium content - Flame atomic absorption spectrometric method》 Related products
This standard specifies a method for the determination of sodium content in potassium fluoroBoricacid by flame atomic absorption spectroscopy (AAS), applicable to the determination of sodium content up to 0.5%. After treating the sample with sulfuric acid, the sodium content is determined at a wavelength of 589.6 nm in the presence of strontium chloride. The standard describes in detail the reagent formulation, instrument use and operation procedures to ensure the reliability of the test results.
