“…It was noted that the %IE increase with the plant extract dose increases. The WL of MS in the blank solution was also found to be higher than those obtained for solutions of NH 2 HSO 3 containing various doses of inhibitor [27]. This indicates that extract is an adsorption inhibitor for the corrosion of MS in solutions of NH 2 HSO 3 .…”

The effect of an aqueous extract of Myrtuis communis on the corrosion behavior of mild steel (MS) in 5% NH 2 SO 3 H solution has been investigated by the following techniques: weight loss (WL), potentiodynamic polarization (PP), electrochemical impedance spectroscopy (EIS), and electrochemical frequency modulation techniques (EFM). The inhibition efficiency (IE) increased with increase in inhibitor dose and increased with rise in temperature. The thermodynamic parameters of corrosion and adsorption processes were calculated and discussed. The adsorption of this extract was found to obey Langmuir adsorption isotherm. The PP tests indicated that the extract is mixed type. The results obtained from the three different techniques were in good agreement. The morphology of the surface was analyzed and discussed.

Tafel polarization method was used to assess the corrosion inhibitive and adsorption behaviours of aminotris(methylenephosphonic) acid (ATMP) for C38 carbon steel in 1 M HCl solution in the temperature range from 30 to 60• C. It was shown that the corrosion inhibition efficiency was found to increase with increase in ATMP concentration but decreased with temperature, which is suggestive of physical adsorption mechanism. The adsorption of the ATMP onto the C38 steel surface was found to follow Langmuir adsorption isotherm model. The corrosion inhibition mechanism was further corroborated by the values of kinetic and thermodynamic parameters obtained from the experimental data.

“…However, the results can be interpreted using the equivalent circuit presented in Fig. 4, which was previously used to model the iron/acid interface [32]. Various parameters such as charge-transfer resistance (Rct), double layer capacitance (Cdl) and degree of heterogeneity (ndl) obtained from impedance measurements are shown in Table 4.…”

The corrosion inhibition of mild steel in a 1.0 M hydrochloric acid solution by 2-(4,5-diphenyl-4,5-dihydro-1h-imidazol-2-yl)-5-methoxyphenol (P1) has been studied in relation to the concentration of the inhibitor, as well as to the temperature, using chemical (weight loss) and electrochemical techniques. All the employed methods were in reasonable agreement. The protection efficiency increased with an increased inhibitor's concentration. The obtained thermodynamic adsorption parameters (∆G * ads, ∆H * ads, ∆S * ads) indicated that this polymer retarded both cathodic and anodic processes through physical adsorption, and blocked the active corrosion sites. It was also found that this compound obeyed the Langmuir's adsorption isotherm.
