Corrosion inhibition and adsorption behavior of two triazole derivatives on API 5L-B carbon steel in CO 2 -saturated 3.5% NaCl solutions was investigated using potentiodynamic polarization, EIS, and EFM techniques. Specimen surfaces were characterized using SEM, EDX, and XRD. Results show that the two compounds are mixed-type inhibitors and inhibition efficiency increases with increasing concentrations. Adsorption of the two compounds chemisorption and obeys Langmuir adsorption isotherm. Activation energy and thermodynamic parameters were calculated. Surface analyses confirm the formation of iron nitrides on the metal surface which supports results obtained from previous techniques.

“…There are some cases where both mechanisms operate occur simultaneously [19]. Generally, S < 1 denotes antagonistic effect while S > 1 denotes synergistic behaviour [44]. Most of the values of S > 1 presented in Table-5 reveals that there pre vailed synergism between GAI and halide ions for carbon steel corrosion control in sulphuric acid.…”

“…However, in the presence of iodide ions, the anions are specifically adsorbed on the steel surface due to the smaller degree of hydration, which allows the protonated CBE molecules to easily approach the steel surface [35,36]. The protonated CBE may adsorb on the steel surface through iodide ions to form organo -iodide -metallic complex such as [Fe-I-CBEH x ]…”

Synergistic Inhibition Effect Between Capsella bursa-pastoris Extracts and Iodide Ions for Q235 Mild Steel in 1 M HCl Solution

Abstract:The inhibition effect of Capsella bursa-pastoris extracts (CBE) and its synergistic effect with KI (CBEK) for Q235 mild steel in 1 M HCl solution were studied by electrochemical measurements. Both CBE and CBEK can serve as eco-friendly, mixed-type inhibitors, and the inhibition efficiency increases with the concentration and temperature. The synergistic parameter (S I ) indicates a cooperative mechanism between the iodide anions and CBE molecules at lower temperature. The associated thermodynamic and kinetic data suggest the presence of CBEK on metal surface mainly through chemisorption at higher temperature. The adsorption processes follow Langmuir isotherm.
