| Abstract: | A method for the determination of nine heavy rare earth elements in the enriched mixture of thulium oxide ytterbium oxide and lutecium oxide by XRF method has been studied in this poper.The samples were prepared by ashing thin film.This method is characterized as it is low cost,economic and simple in standards preparation,and standards can be easily preserved.The accuracy and precision of the results were satisfactory for the demands of prodnction. |
