This standard specifies a method for the determination of lead content in tungsten concentrates using flame atomic absorption spectroscopy (AAS). It is suitable for samples with lead content in the range of 0.005% to 0.30%. The lead content is calculated by measuring Absorbance at a specific wavelength after acidic treatment of the sample. This method does not interfere with the determination of impurities in tungsten concentrates, ensuring the accuracy of the measurement results. The standard provides scientific and effective technical support for the analysis of lead content in tungsten concentrates.
