Abstract
Metals and their alloys are useful structural materials in construction and building industry, due to their peculiar properties. The applications of metals and alloys are, however, bedeviled by corrosion problems. Among the many corrosion preventing methods available, the use of inhibitors stands out, of which their action of inhibitors in corrosion mitigation is through a number of ways, of which adsorption process is one. The knowledge of adsorption process can assist in understanding the mechanism of isotherm. Determination of isotherm best fit has been a subject of intensive debate. Two key parameters commonly employed for such determination are regression coefficient, R2, and free energy, ΔGads value. Many authors have argued the inadequacy of these parameters for the determination. In this chapter, we provide a good insight into how to resolve ambiguity associated with isotherms best fit for adsorption of corrosion inhibitors unto.
