Investigations of the separation of Np,Pa,U,Th and REE in geological samples
Description
In the first part two methods of the radiochemical neutron activation analysis of U,Th and REE trace amounts in geological samples have been studied. They are: cation exchange and extraction, and extraction chromatography. The behaviour of U and Th was also observed and conclusions were made regarding the applicability of the methods for the rocks which are rich in U and Th but depleted of REE. The method is recommended for the selective separation of U and Th. The second part represents an effective separation method for the determination of all REE and Th contents in monazites. 8 refs.; 7 figs.; 3 tabs
