“…By combining 5.0 mL iodide ions with 100 mg/L DSCLE, rutin, and orientin, the mixture synergistically adsorbed on the substrate surface and this led to an enhancement on the inhibition efficiency from 51.2%, 42.5%, 34.0% respectively to 95.7%, 91.0%, and 86.7%. Similar cooperative co-adsorption and upgrade of inhibition efficiency had been reported for Morinda tinctoria leaves extract [356], coconut coir dust extract [352], Mentha pulegium [357], and Artemisia halodendron [358] with iodide ions.…”

“…In Geissospermum leaves [155] as plant extract on C38 steel in 1M HCl, it was examined that the maximum IE of 92% was recorded at 100 mg/L. The IE 84.34% was observed while reviewing the extract of Mentha pulegium [156]. Olive roots, stems and leaves in aqueous extract with 1M HCl were studied with the efficiency of 89.24%, 88.84% and 89.83%, respectively [157].…”

Researchers have just discovered an alternative to synthetic corrosion inhibitors, which are hazardous and terrible for the ecosystem, to prevent rusting in the environment. A metal corrodes when it is subjected to corrosive media (acid, base, or saline) and they deteriorate, leading to failure. The most straightforward and affordable corrosion protection and prevention technique in acidic environments has been proven to be corrosion inhibitors. On industrial surfaces, pieces of machinery, or vessels, these inhibitors slow the rate of corrosion, preventing the monetary losses brought on by metallic corrosion. Recently, attention has been directed to developing ecologically appropriate corrosion retardation methods because inorganic and organic inhibitors are harmful and expensive. Recent studies have focused on green mild steel (MS) corrosion inhibitors that mimic industrial processes in acidic conditions. This presentation briefly covers the many types of corrosion, the corrosion process and the most recent studies on using natural plant extracts as corrosion inhibitors. Since they are safe and cost-effective, green corrosion inhibitors are a new trend in preventing corrosion. These inhibitors are produced from various plant parts, and inhibition efficiency (IE) also depends on them. To ascertain the IE of the corrosion inhibitor, some experiments, including computational studies (quantum calculations and MD simulations), electrochemical measurements (electrochemical impedance (EIS) and potentio-dynamic polarization), surface morphology atomic force microscopy (AFM), scanning electron microscopy (SEM)/energy-dispersive X-ray analysis (EDX) and UV–visible spectroscopy are carried out. It has been demonstrated that the IE is maximum for green corrosion inhibitors compared to synthetic inhibitors. This paper provides an overview of the properties, mechanism of corrosion inhibitors, nature of green corrosion inhibitors and their IE obtained by performing tests. This review article discussion shows that reinforcement with plant extract performs well in aggressive environments, which is evident from electrochemical studies and surface analysis when compared to reinforcement with inhibitors.

“…The effectiveness of organic inhibitors can be enhanced by adding Cl À , I À or Br À ions to the corrosive solutions to results with better protection ability by a possible synergy between these ions and inhibitor molecules. [58,59] This application reduces the amount of inhibitor by obtaining the same or better protection efficiency in corrosive processes. [60] The best synergism is be obtained in the presence of iodide ions since these ions have large volume and easily polarized.…”

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.
