GB/T 4325.16-2013 《Methods for chemical analysis of molybdenum - Part 16: Determination of potassium content - Flame atomic absorption spectrometry》 Related products

This standard specifies methods for the determination of potassium content in molybdenum powder, molybdenum strips, molybdenum trioxide and ammonium molybdate, with a determination range of 0.0010% to 0.150%. After hydrogen oxidation analysis, samples are deionized with potassium chloride solution. Absorbance of potassium is determined at 766.5 nm by flame atomic absorption spectroscopy (AAS). This standard provides a standardized method for the analysis of potassium content in molybdenum materials, which is suitable for mass detection and control of products.
