摘要：
Solvent extraction mechanism of pertechnetic acid with TBP from perchloric acid solutions is discussed. When cyclohexane is used as a diluent of TBP, perchloric acid can be extracted in the form of HClO4(TBP)2 into the organic phase. The TBP extraction of pertechnetic acid competes with perchloric acid and its equilibria are expressed as follows: HTcO4 + 3TBP reversible HTcO4(TBP)3 and HTcO4(TBP)3 + TBP reversible HTcO4(TBP)4.
