“…Besides, increasing temperature results in the desorption of water molecules from the surface and increasing accessibility of the surface sites for the adsorption of inhibitor molecules. The results confirmed that the drug molecules were chemically adsorbed on the MS 54 and are a suitable temperatureresistant corrosion inhibitor.…”

“…Since the semicircle curves were imperfect, the constant phase element (CPE) was utilized instead of an ideal capacitor. The CPE can be calculated using the equation below 54 : where Z CPE represents the CPE’ impedance, j—an imaginary number associating to the square root of − 1, Y 0 —proportionality integral, ω —angular frequency, and n —the CPE exponent which is detailing about the degree of surface inhomogeneity.…”

This study examines the utilization of the expired drug, namely ampicillin, as a mild steel corrosion inhibitor in an acidic environment. The inhibitor was evaluated using weight loss and electrochemical measurement accompanied with surface analytical techniques. The drug showed a potential inhibitory efficiency of > 95% at 55 °C. The inclusion of the inhibitor increased the charge transfer resistance at the steel-solution interface, according to impedance analyses. According to potentiodynamic polarisation measurements, expired ampicillin drug significantly decreased the corrosion current density and worked as a mixed-type corrosion inhibitor. The Langmuir adsorption isotherm was followed by the adsorption of ampicillin drug on the steel substrate, exhibiting an association of physical and chemical adsorption mechanisms. The surface study performed using contact angle and scanning electron microscopy–energy dispersive spectroscopy (SEM–EDS) measurements supported the inhibitor adsorption on the steel substrate.

“…In addition, the comparison of the optical images of Figure b,c indicates that there are a few corrosion spots on the surface of the Ch–Met/GO iron block, whereas the surface of the Ch–Trp/GO iron block is very clean, implying that Ch–Trp/GO exhibits a stronger antioxidation and anticorrosion effect. Combined with Mobin et al’s research, , anodic dissolution results in an iron-bearing positive charge, causing anions to be adsorbed on the metal surface. The adsorbed anions generate exaggerated negative charge clouds on the metal surface, thereby promoting the adsorption of cations.…”

“…Mobin et al synthesized two types of choline-type ILs, and experimental results indicated that the designed ILs were effectively adsorbed on the metal surface to form an adsorption film, thereby inhibiting the corrosion of low-carbon steel on the metal surface. In addition, they designed a novel IL, i.e., l -proline nitrate–graphene oxide nanohybrid (IL–GO), which exhibits an excellent slow-release effect on low-carbon steel in 1 M HCl.…”
