The GB/T 4325.24-2013 standard specifies a method for the determination of tungsten in molybdenum by Inductance-coupled plasma atomic emission spectroscopy (AES). The standard is applicable to the determination of tungsten in materials such as molybdenum powder, molybdenum strip, molybdenum trioxide and ammonium molybdate, and the determination range is 0.005% to 1.50%. The method steps include dissolving the sample with nitric acid, hydrofluoric acid and hydrogen peroxide, and then using Inductance-coupled plasma emission light spectrum method to determine the tungsten content. The required reagents and their specifications are listed in detail in the standard to ensure the accuracy and Reliability of the determination.
