The GB/T 23607-2009 standard stipulates the determination of arsenic, bismuth, iron, nickel, lead, antimony, selenium and tellurium in copper anode mud by Inductance Coupled Plasma Atomic Emission Spectroscopy (AES) method (ICP AES). The method is suitable for the precise analysis of these elements. The sample is first analyzed by aqua regia and saturated ammonium hydrogen fluoride. The obtained test solution is directly determined by ICP AES under specific acidity to ensure the accuracy of the analysis results. The required reagents and solution configuration methods are listed in detail in the standard, including muriatic acid, nitric acid, aqua regia and various standard storage solutions.
