Abstract
A chemical procedure based on reversed phase columnar chromatography and aimed at isolating rare earths from a specimen of solid SAP material is described. The calibration of the spectrographic method is also reported. It has a sensitivity limit of 0.01 mu g per each individual rare earth. The chemical procedure was extensively investigated and checked using radioactive tracers. By using a 5-g sample a solution of pure rare earths was obtained in a chloride medium. The sensitivity limit of the spectrographic method is low enough to permit the use of a sample of reduced weight (e.g. 1 g). (auth)
