This paper describes the principle, method and application of the proportional factor method for the determination of rare earth elements (REE) in geological samples by XRF, The analytical results of this method are compared with REE recommended values in geological standards, and good agreement was observed. Five of the REE (Pr, Tb, Ho, Tm and Lu) have also been determined by interpolation from chondrite-normalized plots, and more satisfactory results were obtained.
