“…It can be seen in the table that Ea is higher in the presence of the inhibitors than in their absence. The modification in the values of Ea may be attributed to the geometric blocking effect of adsorbed inhibitive species on the metal surface [33]. This observation further supports the proposed physisorption mechanism as reported by [34] The values of ∆H and ∆S are given in Table 7.…”

ABSTRACT:The inhibition of mild steel corrosion in sulphuric acid solution was studied with application of Africa parquetina leaves extract (APLE) using Gravimetric, Gasometric and Thermometric measurements. The phytochemical characterization of the leaves extract were also carried out using Gas chromatography mass spectroscopy (GCMS) and Fourier transformation Infra Red (FTIR) analysis. The result showed the presence of phytochemical compounds and functional groups greatly contributed to the inhibitive strength. The inhibition efficiency at optimum concentration 0.5 g/l was 87.78 % and it was increased with the increase in concentration of APLE but decreased with increase in temperature. The adsorption of inhibitor obeyed Langmuir adsorption isotherm and the free energy of adsorption suggested that it was physisorption. Finally, the Dubinnin-Radushkevich isotherm model also suggested the techniques adopted in the corrosion measurement were in good agreement.

“…The values of activation energy enumerated in Table 6 are higher in the presence of the SSE than in its absence. It may be attributed to the geometric blocking effect of adsorbed inhibitive species on the metal surface [28]. Further inspection of Table 6 also revealed that Ea increases with increase in SSE concentration.…”

“…This means that the corrosion reaction will further be pushed to surface sites that are characterized by progressively higher values of Ea in the presence of extracts [29]. The enthalpy, DH ads 0 and entropy, DS ads 0 of activation for the corrosion process, the alternative formulation of Arrhenius equation was used [28,29]:…”

Saccocalyx satureioides as corrosion inhibitor for carbon steel in acid solution

The inhibitory effect of the crude ethyl acetate extract of Saccocalyx satureioides was estimated on the corrosion of carbon steel (X52) in 1 M HCl solution sing weight loss measurement, potentiodynamic polarization, electrochemical impedance spectroscopy and scanning electron microscopy techniques. Potentiodynamic polarization curves indicated that the plants extract behaves as a mixed-type inhibitor. The adsorption of the inhibitor on the carbon steel surface was found to follow Freundlich adsorption isotherm. The free energies, enthalpies and entropies for the adsorption and dissolution process were discussed in details. The inhibiting action increases with increasing concentration of the extract. The results obtained show that the extract of the aerial parts of Saccocalyx satureioides could serve as an effective corrosion inhibitor of carbon steel (X52) in hydrochloric acid medium.

“…Activation energy was calculated from the Arrhenius relation, i.e., plot of ln υ corr vs 1000/T (Figure 1). 26 Both activation entropy and enthalpy (∆S* and ∆H*) were determined from transition state diagram (Figure 2), 27 i.e., plot of ln υ corr vs 1000/T. Table 4 shows that the values for corrosion inhibition process are higher compared to 0.…”
