Most of the carbon dioxide (CO2) corrosion inhibition work published has been based on constituents that
behave as surfactants (e.g., quaternary amines and imidazolines). For these compounds, a relationship
has been found between the concentration for maximum efficiency and the critical micelle concentration
(CMC) and, more recently, with the concentration of maximum adsorption (CMA) on platinum.
This paper shows how the methodology developed to characterize inhibitors based on their CMA values
is still applicable to non-surfactant corrosion inhibitors, which would not show a CMC.
