“…Table 3 shows that the inhibitor efficiency calculated from the EIS data fitting achieves more than 70%, which ever the amount of bark powder added to the test solution. These values are the same order of magnitude to those found in the literature for other natural inhibitors, like as Aniba rosaeodora extract (95%) 16 , Loquat leaf extract (76%) 27 , coffee ground extracts (93%) 39 , and others castor oil compounds, such as Ricinus communis ethanolic extracts (84%) 20 , and castor oil (87%)…”

“…In aqueous solutions, the metal surface is covered by adsorbed water dipoles, which may be displaced and replaced by the inhibitors molecules 16 . The simplest of the isotherms, the Langmuir one, is given in Equation 4 35 and assumes that the adsorbed inhibitor molecules occupy only one site at the metal surface and that there are no interactions between neighboring adsorbed species.…”

“…Because of this, researchers have been focused in investigating the inhibitory properties of easily available and low cost natural products that, in addition, are not harmful to health and to the environment, which are generally denominated green inhibitors 6 . In the literature, several studies are available on the efficiency of leaves or peel extracts as corrosion inhibitors for carbon steel in acidic solutions (generally electrolyte prepared using 37% m/v HCl), like aqueous extracts of mango and orange peel 2 , and alcoholic extracts of Astemisia Mesatlantica oil 7 , Roselle 8 , Eruca sativa 9 , Saccocalyx satureioides 10 , Argemone mexicana 6 , Chrysophyllum albidum 11 , Agavoideae 12 , Tiliacora accuminata 13 , Pimenta dioica 14 , Ilex paraguariensis 15 , Aniba rosa eodora 16 , Ruta chalepensis 17 .…”

Evaluation of Castor Bark Powder as a Corrosion Inhibitor for Carbon Steel in Acidic Media

et al. 2017

The inhibition effect of castor bark powder obtained from Ricinus communis on AISI 1020 carbon steel in acidic media (HCl 0.5 mol.L -1 ) has been studied by electrochemical impedance spectroscopy (EIS), polarization curves, scanning vibrating electrode technique (SVET) and weight loss measurements. Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM) were employed as characterization techniques. The EIS and gravimetric results showed that the inhibitory efficiency increases with inhibitor concentration achieving 83%. Polarization curves indicated that the castor bark powder acts as mixed inhibitor. The adsorption of the powder components on the metal surface follows the Langmuir isotherm. The FTIR analyses indicate the presence of C, N and O heteroatoms, incorporated in functional groups mainly related to the presence of carboxylic acids as ricinoleic acid, which could be responsible for the inhibitory properties of the powder. SEM analyses showed that the corrosion process was retarded in the presence of inhibitor in the electrolyte, which was confirmed by SVET measurements. Therefore, the results indicate that castor bark powder has potential to be a corrosion inhibitor for carbon steel in acidic media.

Corrosion inhibition of carbon steel in 1 M H2SO4 solution by Thapsia villosa extracts

et al. 2016

View full text Add to dashboard Cite

Ethyl acetate extract (EAE) and butanolic extract (BE) of Thapsia villosa were investigated as corrosion inhibitors of Carbon Steel (CS) in 1 M H 2 SO 4 using electrochemical impedance spectroscopy (EIS) techniques, potentiodynamic polarization and weight loss measurements. The effect of temperature on the corrosion behavior of CS was studied in the range of 20-40°C. The experimental results show that EAE and BE are good corrosion inhibitors and the protection efficiency increased with increasing concentration of the extracts, but decrease with rise in temperature. The EAE and BE act as a mixed types inhibitors. The adsorption of extracts on CS surface follow Langmuir isotherm. The apparent energies, enthalpies and entropies of the dissolution process were discussed.

Oil palm empty fruit bunch (OPEFB) extract was evaluated as corrosion inhibitor for mild steel corrosion in 1 M hydrochloric acid using weight loss technique. OPEFB extract was prepared at various concentrations of 0.2–1.0 v/v% for preliminary study. Central composite design (CCD)‐based optimization was engaged to analyze the factors and to maximize inhibition efficiency. The highest inhibition efficiency was estimated up to 99.95%. Fourier transform infrared (FTIR) and scanning electron microscopy (SEM) studies confirmed the presence of active compounds and deposition of extract on metal surface. Thermodynamic study revealed that the adsorption obeyed Langmuir isotherm and inhibition mechanism inclined toward physisorption.
