“…The inhibition efficiency reached 98.2%, the highest value, at the end of the 72 h exposure period with solutions containing 5.0×10 -5 and 1.0×10 -4 M DMT, and after this hour (72 h), the decrease with time was marked in the inhibition values ( Table 2). The time-dependent decrease in the inhibition efficiency is due to the gradual oxidative dissolution of the mild steel in prolonged contact with the corrosive medium and the corrosive effect of chloride ions adsorbable to the inner-Helmholtz layer at the metal-solution interface and the composition of the solution changing near the metallic surface [26][27][28][29][30]. However, at the end of the 120 h exposure period, it is apparently seen that the inhibitor film on the metal/solution interface has begun to be deteriorated and dispersed the frequency, but the protection of the solution containing the DMT inhibitor at the highest concentration is still 93.0%.…”

The Inhibitor Effect of (E)-5-[(4-(benzyl(methyl)amino)phenyl)diazenyl]-1,4-dimethyl-1H-1,2,4-triazol-4-ium zinc(II) Chloride, an Industrial Cationic Azo Dye, onto Reducing Acidic Corrosion Rate of Mild Steel

This study covers the stages of testing whether the azo dye with chemical name (E)-5-[(4-(benzyl(methyl)amino)phenyl)diazenyl]-1,4-dimethyl-1H-1,2,4-triazol-4-ium zinc (II) chloride (DMT), known as Maxilon Red GRL in the dye industry, can be used as an anticorrosive feasible inhibitory agent, especially in industrial areas other than carpet, yarn and fibre dyeing. These test stages consist of the electrochemical measurement techniques such as potentiodynamic polarization, electrochemical impedance spectroscopy (EIS) and linear polarization resistance (LPR) for diverse concentrations and durations. The adsorption of the viewed DMT molecule on the mild steel surface obeyed the Langmuir isotherm. The zero charge potential (PZC) of mild steel was also found to assess the inhibition mechanism in containing DMT solution. The inhibition performance of DMT on the mild steel in a 1.0 M HCl solution was also investigated using methods such as metal microscope, atomic force microscope (AFM) and field emission scanning electron microscope (FE-SEM).

“…In the present study, several adsorption isotherms were assessed, and the Langmuir adsorption isotherm was found to give the best description of the adsorption behavior of the studied inhibitor (Figure ). A correlation between surface coverage ( θ = η EIS %/100) and the concentration of inhibitor ( C ) in the electrolyte can be represented by the Langmuir adsorption isotherm

\frac{C}{θ} = \frac{1}{K_{a d s}} + C

where K ads is constant of adsorption.…”

The inhibition effect of bark resin of Schinus molle (BRSM) on the corrosion of API 5L X70 pipeline steel in hydrochloric acid solution has been studied for the first time by potentiodynamic polarization and electrochemical impedance spectroscopy (EIS) measurements; also, surface morphology has been analyzed by SEM‐EDX. The inhibitor (BRSM) has been characterized by Fourier transform infrared spectroscopy (FTIR). The results show that BRSM is a good inhibitor in hydrochloric acid solution. The maximum percentage inhibition efficiency is equal to 94% at 2 gL−1. The adsorption of BRSM on API 5L X70 pipeline steel surface obeys Langmuir adsorption isotherm, and involves physical adsorption. Polarization curves reveal that BRSM acts as a mixed‐type inhibitor in hydrochloride acid.

“…However, due to serious environmental concerns, in the last few years there has been a big interest for the called "green inhibitors" which includes extracts from plants which also contain heteroatoms and are non toxic, environmentally friendly, non-hazardous, cheaper and readily available. Many of these naturally-occurring inhibitors have been extracted from essential oils contained in plants (21)(22)(23)(24)(25)(26)(27)(28)(29)(30)(31). Thus, Asmaa and El-Dougdoug ( 21) extracted an amido poly amine surfactant from the Melia azedarach seeds oil and used it as a corrosion inhibitor for carbon steel in 2.0M HCl by using potentiodynamic polarization curves and electrochemical impedance spectroscopy.…”

A no-ionic gemini surfactant, namely bis(2-((2-palmitoamidoetil) amino) etil) 1H-imidazol-4,5dicarboxilate, was synthesized from the fatty acids contained in the palm oil and evaluated as corrosion inhibitor for UNS S41425 type supermartensitic stainless steel in presence of H 2 S. Used techniques involved potentiodynamic polarization curves, linear polarization resistance and electrochemical impedance measurements. Additionally, the obtained inhibitor was characterized by Infrared and 1H, 13C RMN spectroscopy. Results have shown that the corrosion rate of the steel was markedly decreased by the addition of the imidazole-type of inhibitor, reaching its maximum efficiency at certain inhibitor concentration, decreasing with a further increase in its concentration. This decrease in the corrosion rate was due to the physical adsorption of the inhibitor on to the steel surface following a Langmuir type of adsorption isotherm, affecting both anodic and cathodic reactions.
