Description
UO2(NO3)2 as a target was irradiated with a 60 MeV/nucleon 18O8+ ion beam, and dissolved in aqua regia. The uranyl was removed from 6 mol/L HNO3 by means of solvent extraction with TBP in benzene, and the barium was separated by BaCl2 precipitation. A 0.4 mol/L solution of HDEHP in n-heptane was used for extraction of rare earth elements from 0.5 mol/L HCl, and back extraction was carried out with an equal volume of 8 mol/L HCl after the organic phase was diluted by adding the same volume of n-heptane. A carrier-free multi-tracer solution containing 18 radionuclides of 12 rare earth elements was prepared
