Abstract
The rare earths together with other impurities are separated from the sample chromatographically on a cellulose column. After the cellulose is ashed, the rare earths are concentrated by coprecipitation with calcium as oxalate and finally with iron as hydroxide and are determined spectrographically by a modification of an iron flux method.
