Mono-, di- and triethanolamines have been studied as inhibitors for pure nickel in sulphuric acid solutions. Potentiostatic polarisation studies have been carried out to follow the corrosion rate in presence and in absence of these amines. A temperature dependence study on the corrosion rates revealed that these inhibitors enhance the activation energy. The anodic and cathodic Tafel slopes were not found to be affected ; this suggests that these inhibitors do not alter the rate determining step of either anodic or cathodic reactions. The adsorption of these amines, offering inhibition, has been discussed in terms of Langmuir isotherm. A detailed investigation on this is presented in this paper
