This standard specifies a method for the determination of cadmium content in molybdenum powder, molybdenum strips, molybdenum trioxide and ammonium molybdate using flame atomic absorption spectroscopy (AAS), with a determination range of 0.0002% to 0.100%. Samples are analyzed in a nitric acid medium, and molybdenum substrates are added to counteract the interference of molybdenum. Absorbance of cadmium is determined at a wavelength of 228.8 nm by AtomicAbsorption Spectroscopy. This standard provides a standardized method for the analysis of cadmium content in molybdenum materials, suitable for material analysis and quality control.
