GB/T 16011-1995 stipulates the flame absorption atomic spectroscopy (AAS) method for the determination of lead sulfide in the air of the workshop. This method first collects lead sulfide dust on a microporous filter membrane with a pore size of 0.8 μm, digests it with nitric acid-perchloric acid, and measures the lead content with an acetylene-air Flame Atomic Absorption Spectrometer (FAAS) at a wavelength of 283.3nm. This standard applies to industrial production sites such as lead mining and smelting, and was later abolished on December 15, 2017.
