| Abstract: | UO 2(NO 3) 2 as a target was irradiated with a 60 MeV/nucleon 18O 8 ion beam,and dissolved in aqua regia.The uranyl was removed from 6 mol/L HNO 3 by means of solvent extraction with TBP in benzene,and the barium was separated by BaCl 2 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 multitracer solution containing 18 radionuclides of 12 rare earth elements was prepared. |
