A method for the quantitative separation and determination of the individual rare-earth elements in the rare-earth minerals which utilizes ion- exchange chromatography (0.5M ammonium lactate in pH = 3.60, 4.60) and pile neutron (JRR-1, 10/sup 11/ neutrons/cm/sup 2//sec) activation is presented. After separation by the ion-exchange method using ammonium lactate at 87 deg C and destruction of the organic reagent, the rare earths were determined by the photometric method (Neothorin). Analyses of three monazites and an allanite were carried out with precision. (auth)
