Abstract
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
