“…The impedance of the CPE, Z CPE , and the C dl can be expressed in eqn (9) and (10), respectively. 59 C dl = Y o ( ω max ) n −1 where Y o , j, ω and n denote the CPE constant, the imaginary number, the angular frequency, and frequency dispersion, respectively. The symbol ω max (rad s −1 ) represents the frequency at which the value of the imaginary impedance reaches the maximum.…”

“…This observation is indicative of better surface coverage and/or thicker inhibitor film and better corrosion protection efficency with the increasing the extract concentration.The surface inhibitor film is responsible for the protecting the metal against corrosion [51] . The low‐frequecncy inductive loop can be assigned to the relaxation process or adsorption/desroption of species like SO 4 2− , H 3 O + , extract molecule sand corrosion products at the MS/electrolyte interface, [44,50–53] as it can translate a rearrangement of molecules on the surface.…”

Adsorption and corrosion inhibitionof Cactus cladode(CC) extract collectedin eastern Algeria from areas of Chetaibi in Annaba on mild steel (MS) in 0.5 MH2SO4 solution were studied with potentiodynamic polarization (PP) and electrochemical impedance spectroscopy (EIS) measurements. The electrochemical stability of surface inhibitor film was investigated by chronoamperometry (CA) technique. The MS surface exposed to thecorrosive medium in the absence and presence of CC extract was examined by scanning electron microscopy (SEM) and energy dispersive X‐ray spectroscopy (EDX) techniques. The potential of zero charge(Epzc) of MS in the presence of CC extract was determined by EIS methodand excess surface scharge of the metal surface was determined. It was found that CC extract has a high inhibition effeciency on the corrosion of MS. The thermodynamic examinations indicated that Kads was 20.88 L g−1 and ▵G0ads was −24.64 kJ mol−1.Thevalue of Epzc confirmed excess positive charge atthe MS surface. The adsorption of extract molecules obeys to Langmuir isotherm. The inhibition efficiency was 91.8 % at 1000 ppm CC extract concentration, while it iscreased to 97.7 % when 1000 ppm KI was added to this solution.The inhibitor film formed over the metal surface has a hydrophobic character.The addition of KI to the inhibited solution stabilizes the surface film and enhances inhibition efficiency.

“…With temperature rising, corrosion potential subsequently shifts to the negative direction, and corrosion current density slightly augments. Moreover, the amplitude of the potential movement is less than 85 mV (Lima et al, 2020), implying that it belongs to the mixed-type inhibitor (Hsissou et al, 2020). Figure 4E presents the weight loss results after 24 h immersion.…”

The parsley extract (PLE) was prepared using absolute ethyl alcohol. The PLE and synergistic iodide were firstly utilized as efficacious corrosion inhibitors to slow down the corrosion rate of carbon steel-Q235 in 0.5 mol/L H2SO4 solution. The anti-corrosion performance was researched by weight loss method, electrochemical tests, surface analysis and quantum chemistry calculation. Results of electrochemical and weight loss tests show that the synergetic PLE and I− exhibit the optimal corrosion inhibition efficiency 99%. The combined inhibitor displays the favorable long-term corrosion inhibition effect, and the inhibition efficiency can maintain more than 90% after 144 h immersion. The introduction of I− makes carbon steel surface with higher negative charge amount, which could be beneficial to the interaction between corrosion inhibitor and Fe atoms. The adsorption behavior obeys the Langmuir isotherm adsorption, and involves chemical and physical adsorption. On the basis of electrochemical consequences and theoretical calculation, the adsorption process and anti-corrosion mechanisms are further explored.
