[en] Complexes of cadmium(II) with glycine and other amino acids have been studied with the help of polarographic and potentiometric techniques. Cyclic voltammetry has been shown to be the best technique for qualitative investigations of complexation reactions. Also one obtains direct evidence for the formation of intermediate species. In the present communication the cyclic voltammetric study of complexation reactions between cadmium(II)-glycine complex system is reported. (author). 4 refs., 2 tabs., 2 figs
