Influence of carbon monoxide, ethylene, acetylene, allyl alcohol and propargyl alcohol on nickel electrodissolution in aqueous sulfuric acid solution
The influence of carbon monoxide, ethylene, acetylene, allyl alcohol and propargyl alcohol on nickel electrodissolution in aqueous 0.5m H2SO4 was studied after the adsorption equilibrium of each of these species at a fixed potential and room temperature had been attained. The hindrance of nickel ele...

| Sumario: | The influence of carbon monoxide, ethylene, acetylene, allyl alcohol and propargyl alcohol on nickel electrodissolution in aqueous 0.5m H2SO4 was studied after the adsorption equilibrium of each of these species at a fixed potential and room temperature had been attained. The hindrance of nickel electrodissolution by carbon monoxide is greater than that resulting from double and triple C-C bond compounds at the same concentration in the solution. Corrosion current, corrosion potential, the amount of dissolved nickel at a constant potential and steady hydrogen evolution polarization data combined with voltammetric deconvolution data provide information about the nickel electrodissolution inhibition capability of these substances in acid solution. |
