“…In recent years, enormous efforts have been devoted to finding efficient corrosion inhibitors. [3][4][5] Most of the corrosion inhibitors investigated are heterocyclic organic compounds containing electronegative functional groups with π-electron systems and heteroatoms like sulfur, nitrogen, oxygen as well as aromatic rings in their structures. [6][7][8] It is generally believed that these molecules adsorb on the metal surface by displacing water molecules on the surface and forming a protective film.…”

Interaction of organic molecules with the surface of metals plays important role in many applications. In particular, surface protective applications need much explanation from both experimental and theoretical point of view. Herein, we have investigated the surface adsorption characteristics and corrosion inhibition behavior of two new benzimidazole derivatives namely 2-(2-Bromophenyl)-1H-benzimidazole (BPBA) and 2-(2-Bromophenyl)-1-methyl-1H-benzimidazole (BPMA) on mild steel in 0.5 M HCl solution using experimental and theoretical approach. Electrochemical and weight loss experiments were used to elucidate the corrosion inhibition potentials of BPBA and BPMA. Attenuated total reflectance-Fourier transform infrared spectroscopy, contact angle, scanning electron microscopy, and X-ray photoelectron spectroscopy measurements were performed to confirm the adsorption of BPBA and BPMA on mild steel surface. Computer simulations were further employed to provide additional insights into the mechanism of interaction between the inhibitors and the steel surface. All the results confirmed that BPMA is a better corrosion inhibitor for mild steel than BPBA in 0.5 M HCl. This new inhibitors could find application industrially during processes such as oil well acidizing for steel protection against corrosion.

“…4). For SO, it has been reported that monolayers of this surfactant on steel can reduce the rate of corrosion (measured as current density) by almost one order of magnitude in acid media [48]. This effect has been linked to the formation of hydrophobic coatings on the surface of iron that prevent the transport of species involved in the redox reaction.…”

Zero-valent iron nanoparticles (NZVI) were synthesized and dispersed in solutions of sodium oleate (SO), sodium laurate (SL), sodium dodecyl phosphonate (SDP), and sodium dodecyl sulfate (SDS). The reactivity of these dispersions was evaluated to assess the impact of surfactants on the reduction rate of hydrophilic reactive black 5 (RB5) and hydrophobic carbon tetrachloride (CT) model contaminants. SO and SL, used at their critical micelle concentration (CMC), lowered the reduction rate of RB5 by two and three orders of magnitude, respectively. SO and SL also decreased the reduction rate of CT by up to one order of magnitude. SDS and SDP, at their CMC, decreased the reduction rate of RB5 by approximately 50-fold, but increased the reduction rate of CT. The decrease in RB5 reduction rate might be explained by the formation of adsorbed surfactant species on the surface of NZVI that could hinder the transport of RB5 and other hydrophilic species. For SO and SL, the inhibition of RB5 and CT reduction might also be explained by the binding of carboxylates to NZVI. The increase in CT reduction rate with SDS and SDP suggests that providing a non-binding lipophilic environment on the surface of NZVI would improve the reduction rate and selectivity towards the reduction of hydrophobic contaminants.

“…this is due to the formation of soluble corrosive product and lack of formation of the passive film on the substrate surface [27]. In the presence of Santolina, the steel shows a more positive potential by adsorbtion on the surface that it helps to slow the corrosion reaction.…”
