GB/T 4372.2-2014 《Methods for chemical analysis of zinc oxide produced by direct process―Part 2：Determination of lead oxide content―Flame atomic absorption spectrometry method》 Related products

This standard specifies a method for the determination of lead oxidation in direct zinc oxidation using flame atomic absorption spectroscopy (AAS), applicable to the determination of lead oxidation in the range of 0.010% to 1.00%. The method summary includes dissolving the sample with nitric acid, measuring the lead Absorbance in dilute nitric acid medium, and calculating the lead oxidation content using the standard Linear dispersion method. The standard also describes the requirements for reagents and instruments in detail, and provides instructions for analytical operations.
