Abstract Rapid determination of rare earth elements (REEs) in geological samples based on X-ray Fluorescence Spectrometry (XRF) is always a difficulty because of the characteristics of the rare earth elements and the limitations of traditional X-ray fluorescence spectrometer. To sovle this problom, a rapid simultaneous multi-element analysis for La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu and Y in soil, rock and deposit has been established using High-Eenrgy Polarized Energy-Dispersive X-ray Fluorescence Spectrometer (HE-P-EDXRF). The pressed powder pellet technique was adoped because of its simple sample preparation. Fifty-nine reference samples were used for the calibration. The measureing conditions of target elements were discussed, including the selection of analytical line and secondary target, matrix effect and spectral overlapping interence of some elements. The correlation coefficients of the linear regression lines for La, Ce, Pr, Nd and Ywere >0.99, and the rest were >0.969. Detection limits for Pr were 4.09 ppm and 0.03~2.13 ppm for the rest. The rock composition standard material GBW07105 was detected for 10 replicate measurements, and the relative standard deviations(RSD) was 0.81%~8.35%. The average relative error of test set between EDXRF data and ICP-MS data was 4.4%~15.4%. In a word, this method could achieve accurate determination of rare earth elements in rock, soil and deposit rapidly, and it is simple in operation.
