Abstract
Reversed phase column chromatography was applied to the separation of Am, Pr, Pm and Eu from 5 to 110 mg of La carrier after coprecipitation. HDEHP and TOPO-xylene solutions held on kieselguhr were used as the stationary phase and the elutions were carried out with 0.1 to 1 N nitric acid solutions. In the HDEHP system, Am can be separated from the rare earths except from Pr. Am can also be separated from Eu in the TOPO system.Keywords
