“…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%.…”

“…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 Cθ=1Kads+C where K ads is constant of adsorption.…”

“…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.…”
