GB/T 4372.7-2014 《Methods for chemical analysis of zinc oxide produced by direct process―Part 7：Determinantion of ferric oxide content―Flame atomic absorption spectrometry method》 Related products

This standard specifies a method for the determination of ferric oxide content in direct zinc oxidation by flame atomic absorption spectroscopy (AAS), which is suitable for the determination of ferric oxide content in the range of 0.010% to 0.10%. The method includes dissolving the sample with muriatic acid and nitric acid, using AtomicAbsorption Spectroscopy measurement of iron in dilute muriatic acid medium, and using the standard Linear dispersion method to calculate the content of ferric oxide. The standard provides reagent, instrument requirements and detailed operation instructions.
