This standard specifies methods for the determination of sodium content in molybdenum powder, molybdenum strips, molybdenum trioxide and ammonium molybdate, with a determination range of 0.0003% to 0.080%. After hydrogen oxidation analysis, samples are deionized in potassium chloride solution. Absorbance of sodium is determined at 589.0 nm using an air-acetylene Flame Atomic Absorption Spectrometer (FAAS). This standard provides a scientific basis for the detection of sodium content in molybdenum materials and is suitable for material analysis and quality control.
