GB/T 4372.3-2015 《Methods for chemical analysis of zincoxide produced by direct process—Part 3：Determination of copper oxide content—Flame atomic absorption spectrometry method》 Related products

This standard specifies the determination method of oxidized copper content in direct zinc oxidation, which is applicable to the range of oxidized copper content from 0.0005% to 0.020%. Absorbance of copper in zinc oxidation samples is measured by flame atomic absorption spectroscopy (AAS), and the content of oxidized copper is calculated by standard Linear dispersion method. The standard describes the reagent requirements, equipment and operation procedures in detail, providing technical support for the determination of trace oxidized copper in zinc oxidation.
