Resumo: The electrochemical behavior of a nickel electrode in 0.5 M H2SO4 in the absence and presence of propargyl alcohol (2-Propyn-1-ol) was investigated. Three different electrochemical methods were used in this paper: potentiometry, partial polarization curves and cyclic voltammetry. A strong interaction between the organic compound and the electrode surface was observed. The incidence of polychromatic light on the electrode surface affects the charge transfer process on it. The anodic reactions related to the electrooxidation of the electrode surface were inhibited by the presence of propargyl alcohol in the medium. The interaction between the organic compound and the electrode surface increases when the system is under illumination. The inhibitory action of propargyl alcohol on the electrooxidation reactions of nickel was observed even at 30 °C in aerated sulfuric acid.
