GB/T 7739.13-2019 "Methods for chemical analysis of gold concentrates, Part 13: Determination of lead, zinc, bismuth, cadmium, chromium, arsenic and mercury content Inductance coupled plasma atomic emission spectroscopy (AES) method" standard specifies a method for the determination of lead, zinc, bismuth, cadmium, chromium, arsenic and mercury content in gold concentrates by Inductance coupled plasma atomic emission spectroscopy (AES) method (ICP-OES). This method uses dissolving samples such as muriatic acid and nitric acid, and uses Internal standafard method to quantify each element to ensure the accuracy and Reliability of the results. This standard applies to the analysis of various harmful elements in gold concentrates.
