GB/T 8152.15-2021 《Methods for chemical analysis of lead concentrates—Part 15:Determination of soluble lead content—Flame atomic absorption spectrometry》 Related products

This standard specifies the method for the determination of soluble lead content in lead concentrates by flame atomic absorption spectroscopy (AAS), which is applicable to the determination of soluble lead content in lead concentrates in the range of 0.3% to 10.5%. The standard details the selective leaching of lead by acetic acid-ammonium acetate solvent and the measurement of lead Absorbance by AtomicAbsorption Spectroscopy in dilute nitric acid medium, providing scientific basis and technical guidance for the accurate analysis of soluble lead in lead concentrates.
