本文研究了PMBP与DPSO的甲苯溶液从高氯酸介质中对Yb(Ⅲ)的协同萃取,测得了协萃络合物的组成为YbA_3B及YbA_3B_2。在298K时各协萃反应的协萃平衡常数及各热力学函数的增量分别为:
In this paper, the synergistic extraction of Yb (Ⅲ) from the perchloric acid solution of toluene solution of PMBP and DPSO was studied. The composition of the complexing complex was found to be YbA_3B and YbA_3B_2. At 298K, the extraction equilibrium constant and the increment of each thermodynamic function of each reaction were:
