GB/T 17087-1997 stipulates the determination of molybdenum content in the air of the workshop by plasma emission Light spectrum method. The standard specifies the requirements for the plasma emission Light spectrum instrument and related equipment to be equipped. The air sample collection steps are described in detail, and the collected samples are processed for detection. Using the plasma emission Light spectrum instrument to detect the characteristic spectral line of molybdenum element, the measurement Spectral line intensity is combined with the standard Linear dispersion to accurately calculate the content of molybdenum in the air of the workshop. The standard provides scientific means for monitoring the air mass of the workshop and evaluating the degree of molybdenum pollution, which is helpful to protect the occupational health and safety of workers.
