✦ Synopsis

The electrodeposition of nickel on vitreous carbon has been studied by electrochemical impedance techniques at low nickel concentrations (10V3-5 x lo-' M) with respect to pH (5 and 3) and anion (Cl-and SO:-). The results suggest a predeposition adsorption of an hydroxylated nickel complex, and passivations due to H,d,and Ni(OH), .An overall mechanism is proposed.

Linear sweep voltammograms for the dissolution of electrodcposited nickel indicate that a mixture of two nickel phases is usually deposited. These two phases have bezn identified as hydrogen-rich p-nickel and the solid solution a-nickel. The anodic charges obtained for each oF these have been used i

## Abstract The aim of the present work was to elucidate the mechanism of electrolytic deposition of Ni on paraffin‐impregnated graphite electrode (PIGE). This process is influenced by H~2~ evolution, which occurs in the same potential region. On the basis of the results obtained by linear and cycl
