Abstract

Polarographic behaviour of some lanthanoids(III) has been studied in N,N-dimethylacetamide. La(III), Pr(III), and Nd(III) showed irreversible, three-electron reduction wave and the other lanthanoids(III), Gd(III), Tb(III), Dy(III), Ho(III), Er(III), Tm(III), and Lu(III) except Sm(III), Eu(III), and Yb(III), gave irreversible, three-electron reduction wave with a pre-wave. The kinetic parameters for La(III), Pr(III), and Nd(III) were determined by means of Koutecky’s method. Sm(III), Eu(III), and Yb(III) showed two-step reduction waves, the first wave being a reversible, one-electron reduction wave. These solvated lanthanoids(III) were investigated also by cyclic voltammetry.
