摘要: Using cyclic voltammetry and single double pulse chronocoulometry the electroreduction of nickel(II) oxidation homogeneous nickel amalgam formed in situ have been studied DMSO its mixtures with water. Nickel(II) current these media exhibits a kinetic character, similar to that observed aqueous dimethylformamide (DMF) solutions. This current, under comparable conditions, correlates well rate exchange solvent molecules corresponding Ni(II)—solvates. With an increase content mixture one observes decrease standard constant Ni electrode reaction by about two orders magnitude. The several pure solvents, related water value, is approximately linearly dependent on free energy transfer ions from solvents.
