The method used is divided into two parts. One part is the determination of La, Ce, Pr and Sm by pretreatment neutron activation analysis. The other part is the determination of Ce, Eu, Tb, Tm, Yb and Lu by direct instrument neutron activation analysis. Pretreatment of samples was carried out by P₅₀₇ extraction chromatography. The decontamination factor of Y was 2×10⁴. A sensitive method for determination of REE in high-pure Y₂O₃ was established.
