Several works have been done and more are on the pipeline on the influence of organic compounds containing polar functions on the corrosion inhibition of metals in various aqueous media. Corrosion inhibition by such compounds is generally attributed to their adsorption on the metal/solution interface. The specific action of an inhibitor depends on the nature of its interaction with metal surface, which causes a change in either mechanism of the electrochemical corrosion process or in the surface area available for the process. Thus, factors such as physiochemical properties of the inhibitors, the nature and surface charge of the metal, solution composition and pH are important considerations. Polymers function as corrosion inhibitors because of their ability to form complexes through their functional groups with metal ions which occupy large area and by so doing blanket the metal surface from aggressive anions present in solution.

Modeling the corrosion inhibition of mild steel in HCl medium with inhibitor of pawpaw leaves extract is presented. The extract was analyzed using gas chromatography-mass spectrometry. Thermometric and gravimetric methods were employed in the corrosion inhibition study. The inhibition efficiency was modeled and optimized using response surface methodology (RSM). It was observed that the free energy of adsorption (∆G ads ) was negative and less than the threshold value of -40 kJ/mol. The adsorption of the extract was spontaneous, and occurred according to the mechanism of physical adsorption. A quadratic model was generated, with optimum inhibition efficiency of 80.29% obtained. The extract was highly efficient in the corrosion control process. It is effective for surface treatment of mild steel in the acid medium. Therefore, it is recommended that pawpaw leaves extract should be employed as corrosion inhibitor in oil well acidizing and surface treatment of mild steel.

“…Corrosion inhibitor is one among them. Recently, plant extracts containing organic compounds having heteroatoms are evaluated for corrosion inhibition [1][2][3][4][5][6]. Azoles and N-methyl-p-aminophenol sulphate have been proved as excellent inhibitors of corrosion for mild steel in acid medium [7,8].…”

The corrosion inhibition effect of acid extract of the pericarp of the fruit Garcinia mangostana on mild steel in hydrochloric acid medium is studied. Using weight-loss data, corrosion rate (CR) and thermodynamic parameters such as energy of activation for corrosion of mild steel (E), heat of adsorption of the inhibitors on the metal surface (Q) and change in free energy (∆G) are calculated. Adsorption isotherm is also recorded between log C and θ. Electrochemical parameters are evaluated from AC impedance and Tafel polarization studies in the presence and absence of different concentrations of inhibitor. Infra-red spectra are recorded for the extract and the adsorption product to find out the changes in the functional group frequencies of the organic components of the extract. The surface morphological changes are analysed using the SEM images. The entire study shows that the pericarp extract of the fruit G. mangostana is a non-toxic, cost-effective corrosion inhibitor for mild steel in acid medium.
