“…Cl ions may be preferentially adsorbed at anodic sites due to electrostatic contact, covering reactive (anodic) sites, at CPC concentrations of 0.00192 M and 0.0077 M, respectively. Furthermore, the lower values of a (Table 2) show that the rate of increase in anodic current density is noticeably slower in the presence of both inhibitor dosages than in the absence of them due to the slow rate of Fe dissolution [31].…”

The corrosion inhibition behavior of cetyl pyridinium chloride (CPC) on mild steel (MS) in 0.5 M H2SO4 solution was examined using the weight loss method and potentiodynamic polarization method. The experimented MS surface was characterized by Fourier Transform Infrared Spectroscopy (FTIR), Field Emission Scanning Electron Microscopy (FESEM), and Atomic Force Microscopy (AFM). Corrosion rate and corrosion efficiency was calsulated via weight loss and potentiodynamic polarization methods where the corrosion rate in 0.5 M H2SO4 , 0.000192 M, and 0.0077 M of CPC solution was 12.09×10-3, 8.23×10-3, 6.63×10-5 (mm/Year), respectively and the inhibition efficiency of 94.42% and 98.54%. FESEM studies demonstrated the corrosion attack on MS surface. Also, the EDX showed the presence of nitrogen of CPC. Thus, CPC acts as an important corrosion inhibitor.

The corrosion inhibition behavior of cetyl pyridinium chloride (CPC) on mild steel in 0.5 M H2SO4 solution was examined using measurement techniques such as Fourier Transform Infra-red Spectroscopy (FTIR), Field Emission Scanning Electron Microscopy (FESEM), and Atomic Force Microscopy (AFM). The studies were carried out within a 25°C temperature range. The surface morphology of the corroded steel samples was investigated using FESEM and AFM. The results show that cetyl pyridinium chloride (CPC), a mild steel corrosion inhibitor, effectively prevents corrosion in 0.5 M H2SO4 and, when present, increases corrosion resistance. CPC has a stronger inhibitory effect on mild steel. The FESEM and AFM images clearly show how surface morphology changes when additives are present. The weight loss results were confirmed by en-ergy dispersive X-ray (EDX) spectroscopy analysis, and a value of 98.54% was obtained from potentiodynamic polarization studies at 0.0077M CPC. CPC acts as an important corrosion in-hibitor.

“…Additionally, the impact of a long spacer chain on enhancing surface coverage was demonstrated by three cationic Gemini surfactants with different spacer lengths, namely G-12, G-6, and G-2 [19]. Additionally, in oil well formation water with existing sulfide ions, additional cationic Gemini surfactant compounds demonstrated corrosion inhibition efficiency between 76 to 81% at 300 ppm [20]. Inhibition of mild steel corrosion by new green surfactants made from erucic acid was examined in a 15% HCl solution [21].…”
