- 論文の詳細を見る
Separation of fission products was carried out by solvent extraction using tri-n-butyl phosphate (TBP). <SUP>144, 144</SUP>Ce, <SUP>91</SUP>Y and <SUP>95</SUP>Zr and <SUP>95</SUP>Nb 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: <SUP>141, 144</SUP>Ce with hydrogen peroxide and nitric acid solution, <SUP>91</SUP>Y with hydrochloric acid solution, and <SUP>95</SUP>Zr-<SUP>95</SUP>Nb with oxalic acid solution. The other nuclides were not extracted by the TBP and remained in the nitric acid and potassium bromate solutions.
