The electrochemical -voltammetry behavior of vanillin, heliotropin, anisaldehyde on the surface of Pt, Au electrodes in acid solution has been studied by means or the electrochemical cyclic voltammetry method. It was round that the electrochemical processes of them are irreversible on both Pt and Au elec- trodes. The electrochemical activity of vanillin is stronger than heliotropin’s and heliotropin’s is stronger than anisaldehyde’s on Pt electrode. While the electrochemical activity of anisaldehyde is stronger than heliotropin’s and vanillin’s is the weakest on Au. The results indicate that when they are used as additives for electroplating, they must be consumptive, and it will improve the leveling ability of plating solution and brightness of the deposition layer.
