“…That is to say, that the %IE in 0.25 M H 2 SO 4 acidic solution decreases when the temperature increases, this behaviour is interpreted as the physisorption happening at the first stage (Zarrouk et al, 2014), (Benabdellah et al, 2006) and this is correlated with increasing the electrical double layer thickness which encloses the surface carbon steel electrode. This establishment of this formation yields a high value for the activation energy and leads to hindrance of metal dissolution by forming a protective film.…”

The impact of cupral compound on steel in presence of deaerated 0.25 M H 2 SO 4 and 0.5M HCl acidic solutions at 298.15K was examined by employing electrochemical measurements. It has been observed that the corrosion efficiency increased by increasing of cupral concentration of the corrosion inhibitor and this enhanced the inhibitory action as mixed type inhibitor. Several different adsorption models were examined which indicate the adsorption of cupral compound as inhibitor on the carbon steel electrode surface follows the Langmuir isotherm equation. The thermodynamic factors governing adsorption, as well as the parameters of kinetics corrosion have been estimated. The role of nanosilica has been observed to reduce the values of current density of corrosion process and this was confirmed by study the surface morphology of electrode via SEM-EDX and AFM techniques by formation a protective layer on carbon steel electrode.

“…However, due to their general aggressively, inhibitors are generally used in these processes to control metal dissolution. There are various organic inhibitors that tend to decrease the corrosion rate of steel and iron in acidic solutions [28,[83][84][85][86]. ILs with imidazolium [87][88][89][90][91][92] and pyridinium cations [93,94] have showed excellent corrosion inhibition performance on mild steel in an acidic environment.…”

Progress and Developments in Ionic Liquids

Ionic liquids (ILs) are molten salts with a melting point of 100°C or below and solely consist of cations and anions. As a kind of novel green solvent, ILs have been obtained broad and deep investigations, and enormous progresses in various ields have been made during the recent 20 years. Despite the fact that the application studies of ILs have been proposed in various ields, no processes have yet been developed to an industrial scale. However, the main interests are still focused on their industrial applications. In this chapter, two perspective applications of ILs in electrochemical ields including additives for metal electrodeposition and inhibitors for metal anti-corrosion were introduced.

Mitigation of corrosion of carbon steel in acidic solutions using an aqueous extract of Tilia cordata as green corrosion inhibitor

The effectiveness of using Tilia cordata extract as a green corrosion inhibitor for carbon steel in 1 M hydrochloric acid solutions was demonstrated by employing some chemical and electrochemical techniques. The surface morphology of C-steel specimens was examined. The results showed that Tilia cordata has corrosion inhibition characteristics with efficiency of 96% as the concentration of Tilia cordata extract increased to 300 mg L -1 . Charge transfer resistance (R ct ) value increases while both the capacitance of the double layer (C dl ) and corrosion current (i corr ) values decrease with increasing the extract concentration. The effect of temperature was studied in the range 30-60°C. Some thermodynamic parameters were calculated and discussed. The adsorption of extract on the C-steel surface was found to obey Langmuir adsorption isotherm. Polarization results showed that the investigated extract acts as mixed type inhibitor. All the different used techniques gave similar results.
