GB/T 16484.5-2009 《Chemical analysis methods of rare earth chloride and light rare earth carbonate - Part 5: Determination of barium oxide content - Inductively coupled plasma atomic emission spectrometry》 Related products
The GB/T 16484.5-2009 standard specifies a method for the determination of barium oxidation in rare earth chloride and carbonic acid light rare earth. The method uses Inductance Coupled Plasma Emission Light Spectrometry (ICP-OES) to melt the sample with anhydrous sodium carbonate, then leach and filtrate it with water, dissolve the filter residue with nitric acid and perchloric acid, and finally excite it with an argon plasma Light source in a dilute nitric acid medium. The measurement range is 0.10% to 2.00% of barium oxidation. This method ensures accurate analysis of barium oxidation content and provides a reliable technical basis for rare earth chemical analysis.
