GB/T 8151.5-2012 《Methods for chemical analysis of zinc concentrates - Part 5： Determination of lead content - The flame atomic absorption spectrometric method》 Related products

Part 5 of this standard specifies methods for the determination of lead content in zinc concentrates, applicable to samples with a lead content range of 0.50% to 6.00%. The method involves dissolving the sample with muriatic acid and nitric acid, and then using an air-acetylene flame and AtomicAbsorption Spectroscopy at a wavelength of 283.3 nm in a dilute nitric acid medium. The standard specifies the use of analytical pure reagents and water of appropriate purity to ensure the accuracy of the measurement results. In addition, the use of AtomicAbsorption Spectroscopy with a certain precision and characteristic concentration is also required for analysis.
