The GB/T 18114.8-2010 standard specifies a method for the determination of the components of fifteen rare earth element oxides in rare earth concentrates. The method uses muriatic acid to acidify the sample after alkali fusion treatment, and then uses argon plasma to excite the sample in a dilute acid medium for Light spectrum determination. Finally, the determination results are obtained by normalization treatment. The standard details the required reagents and their preparation methods, and specifies the reagent concentration and instrument requirements to ensure the accuracy and Reliability of the determination.
