“…The use of corrosion inhibitors is one of the most effective measures for protecting carbon steel surfaces against corrosion in CO 2 environments (Abd El-Lateef et al, 2013a,b,c). Most of the well-known corrosion inhibitors are organic compounds containing nitrogen, sulfur, or oxygen atoms (Cheng et al, 1999;Prabhu, Venkatesha, Shanbhag, Kulkarni, & Kalkhambkar, 2008;Samide, Bibicu, Rogalski, & Preda, 2004;Verma, Quraishi, & Ebenso, 2013;Wang, 2001). It has been found that most of the organic inhibitors act by adsorption on the metal surface (Abd El-Rehim, Ibrahim, & Khaled, 1999;Li et al, 2014).…”

Novel Schiff base amino acid as corrosion inhibitors for carbon steel in CO 2 -saturated 3.5% NaCl solution: experimental and computational study Abstract: The corrosion inhibition and adsorption behavior of some novel Schiff bases based on amino acids on carbon steel in CO 2 -saturated 3.5% NaCl solution at 50°C was investigated using gravimetric, potentiodynamic polarization, linear polarization resistance corrosion rate, and scanning electron microscope (SEM)/energy-dispersive X-ray spectroscopy analysis (EDAX) techniques. Results show that the inhibition efficiency increases when the inhibitor concentration increases. Potentiodynamic polarization curves reveal that the used Schiff bases are mixedtype inhibitors. Experimental data indicate that these Schiff base inhibitors adsorb at the carbon steel/solution interface according the Langmuir adsorption isotherm. SEM/EDAX was used to examine the surface morphology of carbon steel samples in the absence and presence of the inhibitors. Quantum chemical calculations were further applied to explain the experimental results. . His current research interests are quantum chemistry and materials design.

“…Benzothiazole and its derivatives are considered as one of the suitable compounds that be used as inhibitors due to it has donor atoms (N and S) via which bonding with metal ions can occur to form heterocyclic ring-metal complexes. These compounds are used as antioxidant, rust inhibitors and metal de-activators [6][7][8][9]. Aminothiazole derivatives have several useful properties like anti-corrosive [10], antimicrobial [11], antitumor activities [12] and used in sensing applications [13,14].…”

Adsorption and corrosion inhibitive properties of P(2-aminobenzothiazole) on mild steel in hydrochloric acid media

Corrosion inhibition of mild steel in hydrochloric acid solutions using electropolymerized Poly 2-aminobenzothiazole, P(2ABT), was evaluated using weight loss, potentiodynamic polarization and electrochemical impedance spectroscopy measurements at different temperature. Results showed that the inhibition efficiency increases with increasing the concentration of P(2ABT) up to 12.7 9 10 -6 mol L -1 and decreases with raising the temperature. Polarization curves indicate that the studied compound acts as anodic inhibitor. Thermodynamic activation parameters for both dissolution and adsorption processes are calculated and discussed as well as the adsorption isotherms are calculated. Gibbs free energy value confirms the physical nature of the adsorption, also the mechanism of inhibition is discussed. Scanning electron microscopy is used to study the surface morphology of mild steel in hydrochloric acid solution in the absence and presence of 12.7 9 10 -6 mol L -1 P(2ABT). Data obtained from all techniques are in a good agreement with each other.

“…The samples were kept at corrosion potential for 20 min and then corroded for 35 min at current densities in the range 2.3 Â 10 À 3 to 9 Â 10 À 2 mA/cm 2 . Electrochemical measurements [10] have showed that the final potentials reached by samples in the corrosion process are located in the active region.…”
