GB/T 20975.27-2018 "Methods for chemical analysis of aluminum and aluminum alloys, Part 27: Determination of cerium, lanthanum, scandium content Inductance coupled plasma atomic emission spectroscopy (AES) method" standard stipulates the use of Inductance coupled plasma atomic emission spectroscopy (AES) method (ICP-AES) method for the determination of cerium, lanthanum, scandium content in aluminum and aluminum alloys. This method is suitable for detecting the trace content of these three elements in aluminum alloys, and eliminates Matrix interference through working Linear dispersion, providing a reliable technical means for the chemical analysis of aluminum and aluminum alloy materials.
