“…Concern regarding corrosion of carbon steel by H 2 SO 4 has increased in the oil and gas industry because of recent studies concerning transformation of SO x and H 2 S produced during refining and oil extraction into concentrated H 2 SO 4 [3]. There is general consensus that the most practical method to protect metal deployed in such corrosive environments is addition of corrosion inhibitors [4][5][6]. Recently, use of polymers as corrosion inhibitors has attracted great attention.…”

The inhibition effect of two selected polyethylene glycols (PEGs) with different molecular weight and the synergistic effect with rare earth Ce 4? ions on corrosion of carbon steel in 0.1 M H 2 SO 4 solution has been investigated by using electrochemical measurements, scanning electron microscopy, and quantum chemical calculations. The inhibition efficiency (Z%) increased with increasing PEG concentration and molecular weight and decreased with increasing temperature. The adsorption of the PEGs obeyed the Langmuir adsorption isotherm. Potentiodynamic polarization studies showed that the PEGs were mixed-type inhibitors of corrosion by H 2 SO 4 . The results reveal that incorporation of PEGs with Ce 4? ions improved the inhibition performance. The Z% value for the PEGs in combination with Ce 4? was higher than the sum of the Z% values for the individual PEGs and Ce 4? ions, confirming a synergistic effect. Some quantum chemical parameters were calculated to corroborate the experimental results.

The corrosion inhibition effect of Rabeprazole sulfide (RS) on mild steel in 1 M hydrochloric acid (HCl) was investigated using weight loss, potentiodynamic polarization, electrochemical impedance spectroscopy (EIS), and chronoamperometric measurements. Protection efficiency of RS increases with the concentration and decreases with the rise in temperature. Adsorption of RS on mild steel surface in 1 M HCl follows Langmuir adsorption isotherm. The kinetic and thermodynamic parameters governing the adsorption process were calculated and discussed. The polarization results suggest that RS performed as an excellent mixed-type inhibitor for mild steel corrosion in 1 M HCl.

“…The adsorption behavior provides information about the interactions among the adsorbed molecules and their interactions with the electrode surface. [40] A number of adsorption isotherms were evaluated and the Langmuir adsorption isotherm was found to be the best description of the adsorption behavior of the inhibitors studied. The Langmuir isotherm follows the relation [41] :…”

“…The corrosion rate in acid solutions increases exponentially with increasing temperature because of the hydrogen evolution overpotential decreases. [40] The corrosion rate values in the absence and presence of different concentrations of SML at different temperatures and the corresponding inhibition efficiency calculated using Equation (2) are given in Table 4.…”
