Corrosion Inhibition and Adsorption Behavior of Some Azo Dye Derivatives on Carbon Steel in Acidic Medium: Synergistic Effect of Halide Ions

Electroanalytical, quantum and surface characterization studies on imidazole derivatives as corrosion inhibitors for aluminum in acidic media

“…Also, larger values of the energy gap (ΔE L − H ) will provide low reactivity to a chemical species. On the contrary, lower values of the energy gap (ΔE L − H ) will render good inhibition efficiency, because the energy to remove an electron from the last occupied orbital will be low [33]. It has also been reported that increasing values of (μ) may facilitate adsorption of inhibitor on the metal surface by influencing the transport process through the adsorbed layer and therefore inhibition efficiency enhanced [34].…”

N‐methyl‐2‐hydroxyethylammonium oleate ionic liquid performance as corrosion inhibitor for mild steel in hydrochloric acid medium

“…It is well accepted that the presence of halide ions facilitates the adsorption of organic inhibitors by forming bridges between the cation moiety of the inhibitor and the metal surface. [95,96] An increase in inhibition efficiency could be observed in the presence of halide additives if protonated species of the inhibitor were utilized. [95] .…”

“…[95,96] An increase in inhibition efficiency could be observed in the presence of halide additives if protonated species of the inhibitor were utilized. [95] . The specific adsorption of anions is expected to be more pronounced with anions having a smaller degree of hydration, such as chloride ions.…”

Investigation of myrrh extract as a new corrosion inhibitor for α-brass in 3.5% NaCl solution polluted by 16 ppm sulfide

“…The difference in the inhibition efficiencies (% IE EFM ) obtained with the different techniques are a result of the variations between the individual techniques and the different models that were used for the interpretation. 68,69 We performed the EFM technique with applying a potential perturbation signal of amplitude 10 mV with two sine waves of 2 and 5 Hz. The choice for the frequencies of 2 and 5 Hz was based on three arguments (Fig.…”
