ON THE FAST CHEMICAL SEPARATION OF CARRIER-FREE SAMPLES FROM MACRO-AMOUNTS OF PROTON-IRRADIATED RARE-EARTH TARGETS
Journal Article
·
· Radiochimica Acta (West Germany)
The formation of precipitates, which appeared in the body of the cation- exchange resin beds during the chemical separation of carrier-free samples from proton-irradiated cyclotron targets of more than 50 mg of rare-earth oxides, was investigated. The properties and character of this insoluble salt are discussed. A method for such a separation, which avoids the disturbing influence of a precipitate, is given. The sample produced is suitable for beta spectroscopy. The method described is applicable to fairly shortlived rare-earth isotopes, as the procedure can be carried out within 8 hours. (auth)
