| Abstract: | This paper reports direct determination of 11 rare earth(i.e.Y,La,Ce,Pr,Sm,Eu,Gd,Er,Tm,Yb,Lu) in highly pure neodymium oxide by inductively coupled plasma-mass spectrometry.Choosing the optimal operating parameters for instrument.Spectral interferences and matrix effect were discussed.After adding the internal standard element T1,the matrix effect has been basically overcome.The detection limits are 0.019-0.095ng/mL.The recoveries for spiking samples are 81.8%-103.3%. |
