The effect ofOpuntia ficus-indica(Nopal) as green corrosion inhibitor for carbon steel in 1 M HCl solution has been investigated by using weight loss tests, potentiodynamic polarization curves, and electrochemical impedance spectroscopy measurements. Also, scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FT-IR) analysis were performed. The inhibitor concentrations used ranged from 0 to 300 ppm at 25, 40, and 60°C. Results indicated the inhibition efficiency increases with increasing extract concentration and decreases with the temperature, and the inhibitor acted as a cathodic-type inhibitor which is physically absorbed onto the steel surface. In fact, the adsorption of the inhibitor on the steel surface follows the Langmuir adsorption isotherm, indicating monolayer adsorption. The presence of heteroatoms such as C, N, and O and OH groups were responsible for the corrosion inhibition.

The corrosion protection efficacy of electrochemically synthesized poly(2-aminobenzenesulphonic acid) (P2ABSA) on carbon steel in 1.0 M HCl was investigated by electrochemical impedance spectroscopy, Tafel polarisation, scanning electron microscopy (SEM) and FT-IR spectral studies. The polymeric coating was prepared on the steel surface using cyclic voltammetry. Investigations established that P2ABSA effectively prevent the metal dissolution in HCl medium. Polarisation studies revealed that this polymer hinder both anodic and cathodic process of corrosion appreciably. The structures of the chemically and electrochemically synthesised polymers were compared using IR spectroscopy. Morphology of the steel surface confirmed the intact response of P2ABSA on steel surface treated with HCl.

Abstract To strengthen the thermal desalination units and sustainability of their performance and reduce their corrosion during acid cleaning processes to remove the scale layers, economy and nontoxic strategies are needed. Here we clarify how Bladder wrack extract (BWE) can reduce the corrosion mitigations for thermal units (carbon steel part) during the acid cleaning (1.0 M HCl). We find that the performance of BWE extract reached an excellent value (94.2%) at 500 ppm. The rate of electrochemical reactions is very low in the presence of BWE extract, and is consistent with the mass loss method. The activity of BWE extract as a corrosion inhibitor is due to the presence of mixture of organic compounds inside the extract. These compounds were identified by HPLC, SEM and FT-IR analysis.

The inhibition impact of Plantago major leaves extract on carbon steel (CS) which immersed in 0.5 M H2SO4 media was ‎investigated by several methods such as mass loss method (ML), electrochemical impedance spectroscopy (EIS), potentiodynamic ‎polarization (PDP), and electrochemical frequency modulation‎ (EFM). Data obtained from different measurements was showed that %IE enhanced with added the Plantago major extract doses also increased with increasing temperature degree. Thermodynamic adsorption and kinetic parameters of the system were also measured and studied. The ‎adsorption of the Plantago major extract on CS is, according to Temkin isotherm. The ‎ curves from PDP explained that the Plantago major extract is considered as a mixed-type inhibitor. The EIS technique's acquired data verified that the studied extract produced a thin layer that covers and protects the CS surface. Atomic ‎Force Microscopy (AFM) and Fourier Transform Infrared (FT-IR) analysis conformed that Plantago major extract was adsorbed on CS surface. The data obtained from unlike measurements were in good accord.

The extraction of linseed oil (LO) was realized by refluxing method. The extracted oil was identified by gas chromatography method coupled with mass spectrometry (GC-MS). In order to contribute to the protection of the environment, one contemplates to try on LO as a green corrosion inhibitor. The corrosion inhibition of LO was studied by weight loss and electrochemical methods. The obtained results showed that the LO is an effective inhibitor of the carbon steel corrosion in 1[Formula: see text]M HCl solution, the inhibition efficiency increased with concentration to reach 88% at 200[Formula: see text]ppm. Furthermore, the adsorption of the inhibitor on the surface of metal in 1[Formula: see text]M HCl solution was found to obey Langmuir’s adsorption isotherm. The influences of temperature were also studied in the range from 298[Formula: see text]K to 328[Formula: see text]K. The kinetic and thermodynamic data of activation dissolution process were determined and discussed.
