Abstract

Th(NO3)4 was irradiated with 25 MeV/nucleon 40Ar ion beam. The target material irradiated was dissolved in 12 mol/l HCl and the Th in the HCl solution was extracted with 20% (V/V) TBP solution in CCl4 successively, then the TBP solution remaining in the aqueous phase after 4 successive extractions was stripped with benzene. A carrier-free and salt-free multitracer solution containing 38 elements from Be to Bi and 67 radionuclides was prepared. The convenient extraction method was developed for the separation between the target material Th(NO3)4 and the large number of fission products.
