The stability constants of some lanthanide-α-hydroxyisobutyrate complex systems have been determined by cation exchange measurements. Fronaeus' method was used to calculate the consecutive formation constants of the terbium and thulium complex systems in 0.2 M and 1 M ammonium perchlorate. The β3 values of nine lanthanide complex systems have been derived by Schubert's method. The formation constants determined by the cation exchange technique agree with the values found by potentiometric titration. |
