“…There are several reviews on the use of plant extracts as corrosion inhibitors (Migahed and Sabagh, 2009). The literature has shown that plant material such as Aloe Vera extraxt (Eddy & Odoemelam 2009), Aquilaria Crassna Leavees Extract (Helen et al, 2014), Garli (Barreto et al, 2017), Holy Basil (Tulsi) (Kumpawat et al, 2012) and Ginger (Narenkumar et al, 2017) has potential as corrosive inhibitors. Effects of Aloe vera extract on corrosion and kinetics of corrosion process of zinc in HCl solution also studied (Abiola, 2010).…”

The inhibition of corrosion on mild steel in 1M HCl solution was evaluated by utilizing carrot (Daucus carota L.) peels (CP) extract. Study performed by gravimetric and Potentiodynamic polarization techniques. Various concentrations of CP extracts ranging from 0.05, 0.1, 0.2, 0.3, 0.4, and 0.5 (v/v) were used and corrosion rate (CR) on mild steel and inhibition efficiency (IE) were investigated at three temperatures (298K, 308K, and 323K). Corrosion rate increase with the increase in temperature. As inhibitor concentration increases, corrosion rate decreases and IE decreases at elevated temperature. The substantial reduction in CR with the increase in the concentration of CP extract was noted at studied temperatures. However, the increase in the CR at each CP extract along with the increase in the temperature tallied to the increase in kinetic activities at the electrolyte and metal interface. Results show that with the increase of 0.5 g/l CP extract, about 3 times lower CR of mild steel at studied temperatures than in pure 1M HCl solution affirm its robust inhibitive efficiency. Comparatively large change in the anodic Tafel slope and gradual decline in CR with an increase in the CP extract concentration confirmed the restricted dissolution of mild steel. Surface examination suggest that a layer of inhibitor material adsorbed on the surface of mild steel at low temperature is responsible for high IE and this phenomenon is characterized as chemisorption. Weight loss data used to test three well known adsorption isotherm Langmuir, Temkin and Freundlich models and found that data is fitted well to all the models to certain extent however Freundlich Isotherm is found to be best fitted with as the correlation coefficient (R2) values reaching to unity, which showed the applicability of the models to the process.

Carbon steel is used in various applications because of its excellent weldability, good mechanical resistance and low cost. However, its application becomes restricted due to its low corrosion resistance in neutral and acidic media, and it is necessary to use processes to retard the corrosive mechanism, such as the use of inhibitors. Many of the effective synthetic inhibitors used are associated with high cost and some have a high toxicity. In recent years, studies of corrosion inhibitors obtained from natural products have been increasing because they are environmentally sustainable and presents low-cost. Therefore, in the present study, different concentrations of the cocoa shell powder (Theobroma cacao) and hydroalcoholic extract were evaluated as a corrosion inhibitors of SAE 1008 carbon steel in 0.5 mol.L -1 sodium chloride solution. The inhibitory action of the cocoa residue was studied through gravimetric technique and electrochemical impedance spectroscopy (EIS). For the chemical characterization of the inhibitor, the Fourier Transform Infrared Spectroscopy (FTIR) was used. The EIS results showed that the corrosion inhibition efficiency of the steel decreased with the inhibitor concentration, reaching maximum values of 55.97% and 72.93%, for cocoa shell powder and hydroalcoholic extract, respectively. The gravimetric data confirmed the electrochemical results and through the study of the adsorption mechanism it was verified that the adsorbed inhibitor molecules follow the Flory-Huggins isotherm model, for both forms of the inhibitor. For all the concentrations evaluated, the cocoa shell powder did not represent an efficient corrosion inhibitor. In contrast, for the hydroalcoholic extract, at the concentration of 0.44 g.L -1 , a good performance was verified as a corrosion inhibitor of SAE 1008 carbon steel in 0.5 mol.L -1 sodium chloride solution.
