| Abstract: | Copper powder was used as the conductive medium and mixed with rare earth ore powder to produce samples.The standard working curve was established by mixing high-purity rare earth oxides,the relative sensitivity factors of 15 kinds of rare earth elements were obtained,and the compositions of 15 kinds of rare earth elements in various types of rare earth ores were accurately determined.The results showed that the correlation coefficients R2 of linear equations of the working curves of elements were greater than 0.996,and the relative standard deviations(RSDs)were less than 5%.Compared with the results of ICP-MS and ICP-OES,the relative deviations were less than 10%. |
