Abstract
The possibiiity of using C-300 ion-exchange resin for the separation of rare earths was investigated. Trivalent thulium, terbium, and europium were the ions used in the tests. From the results obtained it was concluded that the C- 300 resin can be used for the separation. The rare earths can be collected in pure form with only one cycle of elution using eiuent of pH 3.1, 3.2, or even 3.3, if the atomic numbers of the rare earths differ by a few units. (J.S.R.)
