“…This investigation is in good agreement with the results reported by many researchers [30][31][32][33][34]. The corrosion rate decreases and corrosion inhibition efficiency increases with increase in concentration of ERN inhibitor and the concentration range is 0.0000001 M to 0.001 M for two hours immersion of the mild steel specimens in corroding solution at room temperature (303 K) [35][36][37][38].…”

“…In electrochemical studies, the influence of temperatures indicates a main role to get an idea about the adsorption mechanism of inhibitor molecules on surface of mild steel. In fact, the corrosion inhibition efficiency and corrosion rate is investigated for ERN inhibitor system from 0.0000001 M to 0.001 M with temperatures varying from 303-333 K [38]. The values of inhibition efficiency and the corrosion rate of ERN are given in Table 2.…”

Ropinirole is utilized to forestall sickness and spewing brought about by disease chemotherapy and radiation treatment. It works by hindering serotonin, a characteristic substance in the body that causes queasiness and retching. After lapse, they can be utilized as consumption added substances or inhibitors. The consumption obstruction activity of terminated Ropinirole drug (ERN) on the erosion of mild steel in 1M HCl medium has been assessed by the weight reduction strategy. The weight reduction estimations showed that erosion restraint effectiveness expanded with expanding the convergence of the inhibitor, with greatest security productivity at 0.001 M. The temperature influences the pace of erosion; at high temperatures, the consumption restraint effectiveness diminishes, and erosion is noticed. The robotic parts of consumption obstruction have been concentrated by the potentiodynamic polarization method and electrochemical impedance spectroscopy (EIS). The potentiodynamic polarization strategy uncovers that the inhibitor framework capabilities as a cathodic kind of inhibitor, controlling cathodic responses. An inhibitor can decrease corrosion current due to inhibited reaction rate and increase Linear polarization resistance due to the formation of a barrier on the electrode surface. time., since, within the sight of an inhibitor framework, the charge moves opposition esteem increments and the twofold layer capacitance esteem diminishes. The surface morphology of repressed gentle steel was dissected by filtering electron microscopy (SEM). The natural constituents on the gentle steel surface have been portrayed by energy dispersive X-beam spectroscopy (EDAX). The harshness of the gentle steel surface in cleaned MS, clear MS, and inhibitor frameworks has been described by nuclear power microscopy (AFM). The outcomes have obviously shown that ERN has a repressing limit with regards to decreasing the erosion of gentle steel submerged in hydrochloric corrosive medium.

“…Based on the data, the average deviation factor value was 0.998, which suggests that the mild steel corrosion in the presence and absence of EFB-H deviated by only 2% from the ideal circuit. The deviation observed in the study is far lower than those reported in the literature [8,27,66,67]. Hence it is possible to deduce that the mild steel surface inhomogeneity used in the study was not severe.…”

Innovative Method for Longer Effective Corrosion Inhibition Time: Controlled Release Oil Palm Empty Fruit Bunch Hemicellulose Inhibitor Tablet

This study aims to develop a controlled release oil palm empty fruit bunch hemicellulose (EFB-H) inhibitor tablet for mild steel in 1 M HCl. As plant extracts tend to deteriorate at longer immersion time, limiting its industrial applicability, we attempted to lengthen the inhibition time by forming a controlled release inhibitor tablet. Electrochemical methods (potentiodynamic polarization (PDP) and electrochemical impedance spectroscopy (EIS)) were employed to investigate the efficiency and mechanism of the inhibition. An optimum dosage and immersion time was determined via Response Surface Methodology (RSM). EFB-H tablet was formulated using D-optimal mixture design, and its anticorrosion action at extended immersion time was compared with EFB-H powder. PDP measurement revealed that EFB-H is a mixed type inhibitor. RSM optimization unveiled that the optimum point for a maximum inhibition efficiency (87.11%) was at 0.33 g of EFB-H and 120 h of immersion time. Tablet T3 with EFB-H to gum Arabic to hydroxypropyl methylcellulose ratio of 66:0:34 portrayed the best tensile strength (0.243 MPa), disintegration time (152 min) and dissolution behavior. EFB-H tablet exhibited a longer-lasting inhibition effect than powder, which was 360 h as compared to 120 h for powder. Overall, EFB-H tablet has been successfully developed, and its enhanced effective inhibition time has been experimentally proven.

“…These outcomes demonstrate that [C 4 MIM][OMs] molecules have mobile locations by virtue of which they can interact with the mild steel surface [ 75 ]. Also, the HOMO orbitals are frequently connected with the capability to donate electrons from inhibitor molecules to a relevant acceptor [ 76 ] which is accredited to the high value of E HOMO (- 4.0640) energies compared to E LUMO (−1.0085). The HOMO and LUMO distributions in the [C 4 MIM][OMs] molecules are centralized inside the structure of nitrogen (N + ) atom and equally localizes inside oxygen (O − ) atom [ 27 ].…”

“…The HOMO and LUMO distributions in the [C 4 MIM][OMs] molecules are centralized inside the structure of nitrogen (N + ) atom and equally localizes inside oxygen (O − ) atom [ 27 ]. This shows that the chemical reactiveness of [C 4 MIM][OMs] molecules with Fe (110) plane will probably occur through the portion of [C 4 MIM][OMs] structure comprising nitrogen and oxygen particles like C=N, C –O, C –N, N –N, C –O and the π-electrons [ 76 ]. This present findings reveals that the active sites of [C 4 MIM][OMs] molecules could attached on the mild steel surface.…”
