“…Similarly, Sainia et al, synthesized Polyvinylpyrrolidone Oxime (PVPO) to test its ability as a corrosion inhibitor for mild steel in 1 M H2SO4, at different concentrations and temperatures. The highest corrosion efficiency was found to be 88.39%, with a concentration of 1000 ppm, and a temperature of 303 K (Sainia et al, 2020).…”

The inhibition of corrosion on mild steel in 1M HCl solution was evaluated by utilizing carrot (Daucus carota L.) peels (CP) extract. Study performed by gravimetric and Potentiodynamic polarization techniques. Various concentrations of CP extracts ranging from 0.05, 0.1, 0.2, 0.3, 0.4, and 0.5 (v/v) were used and corrosion rate (CR) on mild steel and inhibition efficiency (IE) were investigated at three temperatures (298K, 308K, and 323K). Corrosion rate increase with the increase in temperature. As inhibitor concentration increases, corrosion rate decreases and IE decreases at elevated temperature. The substantial reduction in CR with the increase in the concentration of CP extract was noted at studied temperatures. However, the increase in the CR at each CP extract along with the increase in the temperature tallied to the increase in kinetic activities at the electrolyte and metal interface. Results show that with the increase of 0.5 g/l CP extract, about 3 times lower CR of mild steel at studied temperatures than in pure 1M HCl solution affirm its robust inhibitive efficiency. Comparatively large change in the anodic Tafel slope and gradual decline in CR with an increase in the CP extract concentration confirmed the restricted dissolution of mild steel. Surface examination suggest that a layer of inhibitor material adsorbed on the surface of mild steel at low temperature is responsible for high IE and this phenomenon is characterized as chemisorption. Weight loss data used to test three well known adsorption isotherm Langmuir, Temkin and Freundlich models and found that data is fitted well to all the models to certain extent however Freundlich Isotherm is found to be best fitted with as the correlation coefficient (R2) values reaching to unity, which showed the applicability of the models to the process.

“…Others have investigated the corrosion inhibition efficiency (CIE) of chitosan for MS in hydrochloric acid, [ 15 ] glucose‐based polymer, [ 16 ] Pectin for steel in acid, [ 17 ] and chitin for steel in the acid, [ 18 ] PVP for CS in the HCl medium, [ 19 ] PVP as for CS in salt solution, [ 20 ] PVP for CS in the HCl medium, [ 21 ] PVP‐Oxime for MS in the H 2 SO 4 medium. [ 22 ] Libya‐based Morus nigra L. was investigated as CI for MS in 1.0 M HCl and a maximum of 94.9 % CIE was achieved at 10 % plant extract. [ 23 ] Black Mulberry leaves extract was investigated as CI for the aluminum metal in 2 M HCl solution and shows a 93 % CIE at 2000 ppm of plant extract.…”

Morus nigra (Mulberry leaves) was tested as a green inhibitor for mild steel (MS) in 0.5 M HCl by theoretical, surface study, and experimental techniques. The impedance, polarization, microscopy, Langmuir, and DFT (computational) techniques were used for the adsorption and corrosion inhibition study. The experimental and theoretical study supports each other results. Adsorption parameters were observed by Langmuir, Gaussian09W (DFT), and BIOVIA Materials Studio softwares. The surface study was carried out by metallurgical microscopy technique. The theoretical study includes chemical potential, electron‐donating power, chemical hardness, HOMO, LUMO, metal inhibitor interaction energy, adsorption energy, etc. UV‐visible, NMR, and FTIR studies show that aspartic acid is the major constituent present in the mulberry leaves extract. A 91.62% corrosion protection was provided by the Morus nigra at 1000 ppm. Polarization study proved mixed inhibition. The green inhibitor follows both physical and chemical modes of adsorption. The biochemical and chemical oxygen demand of unused acid left after the gravimetric study was found in an acceptable range.

“…Improving the recovery factor of tight oil reservoirs can effectively alleviate energy problems such as insufficient energy supply. Acidification is one of the important measures for oil well stimulation [1,2]. However, the acid used in acidification usually contains strong corrosiveness, which will destroy the oxide film on the metal surface and increase the probability of pitting corrosion on the metal surface, seriously damaging tubing and mechanical equipment, thus prolonging the workover period and increasing the economic cost [3], and may also lead to downhole safety accidents.…”

In the process of petroleum exploitation, in order to effectively inhibit the corrosion damage of acid to metal equipment. Mannich base corrosion inhibitors are generally added to inhibit the corrosion damage of acid. In order to enhance the solubility of Mannich base corrosion inhibitor. This paper intends to introduce hydrophilic groups to enhance the solubility of the Mannich base corrosion inhibitor. In this paper, two efficient corrosion inhibitors 3-(2-hydroxyethylamino)-1-phenylpropan-1-one (MY1) and 3-(2-aminoethylamino)-1-phenylpropan-1-one (MY2), were synthesized based on the Mannich reaction, using formaldehyde, acetophenone and ethanolamine/ethylenediamine as reaction raw materials. The corrosion inhibition performance of the inhibitor on N80 steel in 15% (mass fraction) hydrochloric acid solution was studied by means of the static weight loss method, electrochemical test and optical contact angle analysis. It could be seen from the static weight loss method that the corrosion rate in the hydrochloric acid solution before and after adding 0.7% (mass fraction) corrosion inhibitor concentration decreased from 129.39 g·m−2·h−1 to 1.45 g·m−2·h−1 and 2.79 g·m−2·h−1, respectively. The corrosion inhibition rate could reach 98%, indicating that both inhibitors had good corrosion inhibition performance, and the corrosion inhibition effect of MY1 was better than that of MY2. It was found from the electrochemical tests that the two inhibitors were mixed corrosion inhibitors mainly inhibiting the anodic reaction, and both inhibitors belonged to spontaneous adsorption, and their adsorption behaviors followed the Langmuir adsorption isotherm. In addition, the surface of N80 steel was characterized by SEM, EDS elemental mapping and contact angle measurement. The results show that a dense hydrophobic film is formed on the surface of the steel sheet after the addition of a corrosion inhibitor, which prevents corrosion.
