摘要：

The distribution of 141Ce, 152,154Eu, 160Tb and 168Tm between aqueous solution in perchloric, nitric or hydrochloric acids and dibutylphosphoric acid solution in benzene was studied. Beyond a certain limiting concentration of the mineral acid in the aqueous phase, a change of the extraction mechanism takes place, the MeX3(HDBP)3 complexes being extracted by the solvation mechanism (X = ClO4, NO3, Cl). This extraction mechanism is independent on the initial concentration of hydrogen ions and on the atomic number of rare earth elements. © 1969.
