GB/T 4698.27-2017 "Methods for chemical analysis of titanium sponge, titanium and titanium alloys, Part 27: Determination of neodymium content Inductance coupled plasma atomic emission spectroscopy (AES) method" specifies the method for the determination of neodymium content in titanium sponge, titanium and titanium alloys using Inductance coupled plasma emission Light spectrum method (ICP-OES), which is suitable for the determination of neodymium content between 0.10% and 3.00%. The standard details the sample pretreatment process, including the use of sulfuric acid and nitric acid to dissolve and titanium oxide, and then the measurement of neodymium emission intensity at the specified wavelength by ICP-OES technology to finally calculate the neodymium content. This standard applies to mass detection and analysis of related materials.
