“…This effect has a contrary impact on the corrosion rate of the metal in various concentrations as corrosion rate values were found to be decreasing from 0.934 in 1 M HCl solutions to 0.083 and 0.011 ppm for aconitine and tubocurarine alkaloids, respectively, as earlier observed in a similar work [12][13][14][15]. This observation could generally be attributed to the strong binding power, large surface area coverage of both inhibitors on the low carbon steel surface due to adsorption, and significant water molecules substitution at the metal arena [12,[16][17][18][19]. Comparing inhibition ).…”

“…Fig. 4(a-b) reveals a Nyquist plot with only one capacitive loop, and this may be due to the presence of just a single charge transfer [17][18][19][20][21][32][33][34][35]. It was also observed that the size of the loops increased with the rise of both tubocurarine and aconitine alkaloid concentration up to 1500 ppm, which indicates that both inhibitors were adsorbed on the low carbon steel surface, and the surface area exposed to the 1 M HCl was reduced [14][15][16]22,[36][37].…”

“…The plots and values obtained from the potentiodynamic polarization experiment are presented in Table 4. Values are seen to increase with increasing inhibitor concentration, an indication that depicts decreasing diffusion rate for reactants to the surface of the metal and decreasing electrical resistance of metal surface due to strength of bonding to the substrate, cross-linking ability of the inhibitors, and solubility of the 1 M HCl environment [19,24,[46][47][48]. In addition, as shown in Fig.…”

Corrosion is an enormous challenge in all sectors of the economy, especially to those working with metals. The research on the adsorption and inhibition analysis of aconitine alkaloid (ACA) and tubocurarine alkaloid (TBA) as eco-friendly inhibitors of pitting corrosion in ASTM – A47 low carbon steel in HCl acid was carried out under the following experimental methods: gravimetric method, gasometric method, electrochemical impedance spectroscopy, potentiodynamic polarization, and scanning electron microscopy. Results revealed good inhibitors as inhibition efficiencies were recorded at 98.8% and 91.2% at a maximum inhibitor concentration of 1500 ppm for tubocurarine and aconitine alkaloids, respectively. The inhibition efficiency was found to increase with increasing inhibitor concentrations indicating a strong binding between inhibitor molecules and ASTM – A47 low carbon steel in HCl acid. Electrochemical data strongly supported the efficacy of both inhibitors as earlier presented by the chemical methods as a trend in values of charge transfer resistance, double layer capacitance, corrosion potential, and corrosion current density were in accordance with standards for a good inhibitor. The inhibitors were seen to be spontaneous, stabled, endothermic and physically adsorbed. Adsorption of the inhibitors on metal surface obeyed Langmuir, El-Awady, Freundlich, and Temkin adsorption isotherm as regression values were approximately unity.

The anticorrosive activity of Combretum indicum (CI) leaf extract has been examined on mild steel corrosion in 1M HCl by using weight loss and electrochemical measurement techniques. The results of these experimental techniques have consistent in confirming the effect of the CI leaf extract on corrosion inhibition and a mechanism for the inhibition was proposed. The dissolution rate of steel in acidic solution was found to be sensitive to the concentration of CI leaf extract and the corrosion rate reduces when the concentration of CI leaf extract is increased and reaches the high protection efficiency. The potentiodynamic polarization study confirms the mixed mode of inhibition. Ultraviolet-visible (UV) and Fourier-transform infrared (FTIR) spectroscopic techniques were performed to evaluate the phenomenon of adsorption in the plant extract and the functional groups. The surface morphology analysis (SEM) further corroborates the adsorption of inhibitor molecules over the metal surface.

“…From Table 3 it is evident that an increase in temperature increased the I corr values, and the CR, indicates that corrosion inhibition was retarded by temperature. The CR values acquired at three temperatures allow calculating the Arrhenius activation energy E a based on the following equation 5 as borrowed from [46]: (5) where logA is the Arrhenius constant which depends on the metal and the electrolyte, T is the absolute, and a logCR log , 2.303 ) and entropy ( ) of activation of the corrosion process in acidic media were calculated using the following transition state equation as borrowed from [49]:…”

A Rangoon creeper flower (RCF) extract was investigated as green inhibitor to mitigate corrosion of mild steel in 1 M HCl solution. In the study, electrochemical impedance spectroscopy, polarization techniques, and gravimetric methods were used. A significant reduction in the corrosion rate with increased concentrations of the RCF extract at varied temperatures was noted. The inhibition of the corrosion process is due to the adsorption of the RCF extract on the mild steel surface. Polarization measurements revealed that the RCF extract was an inhibitor of a mixed type. The adsorption of the inhibitor on the mild steel surface followed the Langmuir isotherm. Functional groups present in the RCF extracts were recognized by using Fourier transform infrared spectroscopy. Scanning electron microscopy was applied to examine the surface morphology of mild steel.
