The polarographic method has been applied to the study of the coordinated systems Cd(II)-neutral valine and Cd(II)-valinate ion in aqueous medium and I = 1.0 mol l-1 (NaClO4). The stability constants of the complexes were determined as: [Cd(HV)]2+ (β10 = 7 ± 0.5), [Cd(HV)2]2+ (β20 = 24 ± 4), [Cd(HV)3]2+ [β30 = (1.5 ± 0.32) . 102], [Cd(V-)]+ [β01 = (4.1 ± 0.3) . 103], [Cd(V-)2] [β02 = (1.3 ± 0.2) . 107], [Cd(V-)3]- [β03 = (1.5 ± 0.3) . 109], [Cd(HV)(V-)]+ [β11 = (4.3 ± 0.8) . 104], [Cd(HV)(V-)2] [β12 = (1.7 ± 0.3) . 107] and [Cd(HV)2(V-)]+ [β21 = (1.2 ± 0.3) . 105].
