“…This behavior is due to that the inhibitor was adsorbed physically on the corroded metal surface (Fe 2+ ) and non‐corroded Fe surface (Fe 0 ), that is completely consistent with the results and explanation described by Ammar and El‐ Khorafi . On the other hand, the inhibition efficiency was decreased slightly with increasing the concentration of inhibitor at the same temperature, (303 to 333 K), this is due to segregate the adsorbed HAT molecules from the metal surface because of the weak physically interaction between the components, which are leads to exchange between inhibitor molecules and Cl − or H 2 O in the corrosive solution …”

A triazole inhibitor, 3,5-di(4-hydroxyphenyl)-4-amino-1,2,4-triazole (HAT), was investigated as an anticorrosion material for carbon steel in Iraqi kerosene tanks using Tafel polarization method at (303, 313, 323, and 333 K) and (100-500 ppm) in kerosene medium. The results showed that the highest inhibition efficiency was obtained at 86.74% in 100 ppm and 333 K. The studied thermodynamic parameters show that the adsorption isotherm of the HAT inhibitor on the steel surface was identical to Langmuir isotherm. The polarization behavior revealed that this inhibitor acts as a mixed-type inhibitor, the corrosion inhibition data have been measured and discussed in details to predict the performance of the inhibitor. The morphology of the inhibited surfaces was characterized using scanning electron microscopy/energy dispersive X-ray spectroscopy (SEM/EDS) and an atomic force microscope (AFM). Furthermore, the Fourier transform infrared (FT-IR) technique was used to show the interaction between HAT and the steel surface. Also, the antimicrobial activity of HAT inhibitor against some types of corrosive bacteria was examined. In addition, quantum chemical parameters were calculated by density functional theory to reveal the active centers of the inhibitor and clarify the correlation of molecular structure of the inhibitor and its efficiency of the inhibition.

“…In order to mitigation corrosion problems, several methods were adopted such as coating, anodic protection and the use of inhibitors [4]. Up to now, the employment of inhibitors has still the most popular topic of research in the field of corrosion, in view of their ease of application and their high effectiveness [5][6][7]. Different kind of inhibitors have been used over the years such as inorganic and organic compounds, but due to their toxicity and restrictive environmental regulations, the development of environmentally corrosion inhibitors has become highly recommended [8][9][10].…”

The current investigation presents the corrosion activity of Elaeoselinum thapsioides (BEET) butanolic extract in 1 M HCl as a novel green source of corrosion inhibitor, and it's synergetic effect with another butanolic extract of Reutera lutea (BERL), whose belongs to the Apiaceae family. Weight loss measurements, potentiodynamic polarization and electrochemical impedance spectroscopy (EIS) measurements have been done to study the inhibition efficiency. The obtained results showed that the inhibition efficiency of BEET alone increase with concentration and reached a value of 82% at 900 ppm. However, the maximum protection efficiency was more than 92% with the combination of BEET and BERL inhibitors. The rise of temperature caused a significantly decreased of inhibition efficiency. The potentiodynamic polarization results revealed that the extract functions as mixed-type inhibitor with predominance at anodic domain, and the adsorption process of the extract follows Langmuir isotherm. In addition, EIS shows that increasing the concentration of the inhibitor leads to an increase of the charge transfer resistance and reducing the double layer capacitance. The synergistic factor (S) was used to investigate the synergistic behavior of the selected inhibitors.

“…However, the phase angle diagram exhibited two time constants when the concentration of PAA increased to 400 or 800 ppm, indicating that one PAA protective layer formed on the iron surface. The group of phase angle diagrams demonstrated that the values of the phase angles decreased with increasing concentrations of PAA, which indicated that the formed PAA layer was not compact . This phenomenon may be the main reason why the inhibition efficiency of PAA was low.…”

Commonly used organic inhibitors face one common problem: Environmental friendliness and excellent inhibition efficiency cannot be simultaneously realized. Here, we report one facile method that can be used for the in situ synthesis of one stable polyacrylic acid/zinc colloidal particles (PZCPs) doped polyacrylic acid (PAA) through the electrostatic interaction between polyacrylic acid and Zn 2+ as a corrosion inhibitor of iron. The results of microstructure characterization indicated that the diameter of the colloidal particles was around 150 nm. The various electrochemical experimental results indicated that PZCPs doped PAA exhibited excellent inhibition efficiency, and the maximum inhibition efficiency was 82.3%. The PZCPs doped PAA exhibited higher inhibition efficiency than PAA because the adsorption ability of PZCPs doped PAA was stronger than that of PAA and the formed PZCPs doped PAA inhibition layer on the iron surface was thicker and denser than the PAA inhibition layer. Given the eco‐friendly, facile synthesis, excellent inhibition efficiency, and low price, this strategy to synthesize effective inhibitors will find widespread application in the anti‐corrosion industry.
