Abstract Stability constants of the fluoride complexes of Pu(III), Sm(III) and Bi(III) in 1.0M NaClO4/HClO4 medium at 23±1°C have been determined by potentiometry using a fluoride ion-selective electrode. Plutonium was reduced to the trivalent state using quinhydrone with an excess to serve as holding reductant. The log values of concentration stability constants log β1, log β2, and log β3 are 3.58, 6.40 and 12.61 for Pu(III), 3.23, 5.81 and 10.54 for Sm(III) and 3.69, 6.13 and 11.04 for Bi(III), respectively. The log β2 values in all these cases have very large deviation and may be taken only as rough estimates.
