A method is given for the quantithtive separation and determination of individual rare earth elements in minerals. The method utilizes ion-exchange chromatography (0.5 M ammonium lactate in pH = 3.50, 4.30, 87 deg C) and pile- neutron (lO/sup 1//sup 1/ n/cm/sup 2//sec) activation. The rare earths are extracted by the 5,7-dichloro-8-quinolinol method from each fraction and determined photometrically by the Neothorin method after destroying the organic reagent. Analyses of gadolinite, xenotime, fergusonite, euxenite, and yttrialite were carried out with precision. (auth)
