“…1b), three molecules all display a strong absorption band at 1670 cm À1 , indicating CQN vibration absorption peak formed by the Schiff base reaction of the amino group and the aldehyde group. 35 The bands at 1182 cm À1 and 1033 cm À1 are the characteristic peaks of the acid -SO 3 group, which indicate that the Schiff base reaction mainly occurs at the amino site on the CS molecular chain and does not destroy the main chain structure of CS-IL. In the FTIR spectrum of CS-IL-Cin, the peaks at 754 cm À1 and 688 cm À1 are the single substitution characteristic peaks of the benzene ring in cinnamaldehyde and the vibration peaks of CQC, respectively, indicating the successful grafting of cinnamaldehyde on the chain of CS-IL.…”

“…In these circumstances, the inhibitory efficiency decreases with the rise in temperature of the electrolytic medium. According to several authors, the latter behavior is due essentially to the desorption of inhibitor molecules, which is to say, the reduction of the inhibitor capacity to be adsorbed on the metallic surface at the elevated temperatures [55,[77][78][79].…”

According to the literature, the works on the inhibition of aluminum alloy corrosion using naturally occurring compounds are limited. For this, the inhibiting effect of oil mill liquid by-product (OMW) on the corrosion of 3003 aluminum alloy (AA3003) in molar hydrochloric acid solution was evaluated using electrochemical techniques. In parallel, a computational approach based on DFT/B3LYP and Monte Carlo methods was used to understand the inhibition process under electronic and atomic scales, respectively. The experimental results reveal that OMW has a good inhibiting effect on the corrosion of AA3003 alloy in the tested solution and acts as a cathodic inhibitor. The inhibitory efficiency increases by increasing OMW concentration to attain 89% at 6.0 ppm. The effect of temperature shows that the inhibition efficiency of OMW decreases with temperature rising. Nevertheless, a good prevention capacity of 83% is obtained at 338 K. Such interesting achieved protection property was attributed to the adsorption of OMW constituents onto the alloy surface via a mixed physichemisorption process. This process is found to obey the Langmuir adsorption isotherm. Furthermore, the activation thermodynamic parameters of the corrosion process of AA3003 alloy were also determined and discussed. The computational outcomes outlined the ability of the OMW components to interact favorably with the metal surface, hence the formation of a protective layer, which justified the observed inhibition behaviors. Conferring to the present study, OMW can be used as a good green corrosion inhibitor for AA3003 alloy in the acidic medium.

“…The corrosion inhibitors from natural plants and animals have the advantages of nontoxicity, low pollution, and low cost [27,28,29]. Therefore, natural substance could be seen as a promising source of corrosion inhibitor [30,31,32]. In the last few years, several naturally occurring polymers have been used as anti-corrosion in a corrosive environment, including starch, chitosan, cellulose, etc.…”

A novel lignin-based quaternary ammonium material (lignin-DMC) with excellent corrosion resistant behavior was synthesized by grafting DMC (methacrylatoethyl trimethyl ammonium chloride) onto kraft lignin. The structure and anti-corrosion performance of lignin-DMC was investigated using many methods, for instance the scanning electron microscope (SEM), atomic force microscopy (AFM), charge density analysis, molecular weight analysis, electrochemical methods. Fourier-transform infrared spectroscopy (FT-IR) confirmed the formation of the lignin-DMC. The experiment results indicated that maximum corrosion inhibition efficiency (87.65%) occurred at a concentration of 75 mg/L via weight loss measurement. Polarization curves indicated that lignin-DMC was a mixed-type inhibitor with an efficient anti-corrosion performance in an acid medium. Electrochemical impedance spectroscopy (EIS) results indicated that lignin-DMC could create a shielding effectiveness and achieve a protective effectiveness in the HCl solution. Moreover, lignin-DMC displayed a physical and chemical adsorption process between 20 KJ/mol and 40 KJ/mol, which followed the Langmuir adsorption isotherm model.
