Artykuł
Reduction of Ni(II) ions in the presence of potentially terdentate diamino acids (2,3-diaminopropionic acid, 2,4-diaminobutyric acid, histidine) was studied polarographically. The complex species re duced on a mercury electrode and their electrochemical parameters were determined. Electrochemi cal behaviour of the particular species strongly depends on the donor set bound to the metal ion. Evaluated stability constants show that the studied systems have different thermodynamic stabilities even for the same donor system involved when chelate rings differ in size.
