“…3 shows that halide additives, namely KCl, KBr and KI, generally improved the inhibition efficiency of the extract at the temperatures studied. Such enhancement in the efficiency of organic inhibitors in the presence of halide salts has been previously observed and was ascribed to the synergistic effect [16][17][18]. …”

“…The adsorption mechanism for a given inhibitor depends on such factors, as the nature of metal corrosion medium, the pH and the concentration of the inhibitor as well as the functional groups present in its molecule [7]. The corrosion inhibition process is based on the adsorption of the amino acid molecules on the active sites and/or deposition of the corrosion products on the alloy surface [8,9].…”

“…The equivalent circuit diagram that is used consists of the R s , R t , and CPE are "resistance of solution", "resistance of charge transfer" and "constant phase element" respectively. Thus, the CPE represents the capacitance of electrical double layer "Cdl" that explains the behaviour of the whole heterogeneous system and to yield more accuracy when applied to the experimental results 44 . The circuit diagram placed R t in parallel to the CPE which is defined by Y 0 which is the coefficient of CPE and n is an exponent or could be defined as the phase shift to give a picture of the degree of inhomogeneity of the surface 45 .…”
