| Abstract: | A new method for the analysis of trace 14 rare earth elements in cerium oxide(99.99%) by inductively coupled plasma-atomic emission spectrometry(ICP-AES) was established.The spectra interferences were investigated in detail,then the proper analysis lines were selected.Simultaneously,matrix matching effect was analyzed by determining samples,and the detection limits range from 0.013 to 0.317 μg/mL depending on the elements.This method was simple,fast and exact,which had the reference value on analyzing practical samples. |
