Description

Separation of fission products was carried out by solvent extraction using tri-n-butyl phosphate (TBP). 144, 144Ce, 91Y and 95Zr and 95Nb were extracted with TBP from a freshly prepared nitric acid-potassium bromate solution. These nuclides in TBP were successively back-extracted with various aqueous solutions: 141, 144Ce with hydrogen peroxide and nitric acid solution, 91Y with hydrochloric acid solution, and 95Zr-95Nb with oxalic acid solution. The other nuclides were not extracted by the TBP and remained in the nitric acid and potassium bromate solutions. (author)
