“…The decrease in the protection power could be related to the desorption of PAC and PAC/CuONPs from the C-steel interface at a higher temperature. This phenomenon indicates that, at a higher temperature, PAC and PAC/CuONPs molecules fundamentally adsorb on the C-steel surface by physisorption [60]. On the other hand, the protection capacity of PAC/NiONPs (Figure 6B,C) increases from 98.1% to 99.3% with a rise in temperature.…”

Novel environmentally-friendly corrosion inhibitors based on primary aminated modified cellulose (PAC) containing nano-oxide of some metals (MONPs), for instance iron oxide nanoparticles (Fe3O4NPs), copper oxide nanoparticles (CuONPs), and nickel oxide nanoparticles (NiONPs), were successfully synthesized. The as-prepared PAC/MONPs nanocomposites were categorized using Fourier transform infrared spectroscopy (FT-IR), transmission electron microscope (TEM), field-emission scanning electron microscopy (FE-SEM), energy-dispersive X-ray spectroscopy (EDX), X-ray diffraction (XRD), and selected area diffraction pattern (SAED) techniques. The data from spectroscopy indicated that successful formation of PAC/MONPs nanocomposites, as well as the TEM images, declared the synthesized PAC/Fe3O4NPs, PAC/CuONPs, and PAC/NiONPs with regular distribution with particle size diameters of 10, 23 and 43 nm, respectively. The protection performance of the as-prepared PAC and PAC/MONPs nanocomposites on the corrosion of C-steel in molar HCl was studied by the electrochemical and weight-loss approaches. The outcomes confirmed that the protection power increased with a rise in the [inhibitor]. The protection efficiency reached 88.1, 93.2, 96.1 and 98.6% with 250 ppm of PAC/CuONP, PAC/Fe3O4NPs, and PAC/NiONPs, respectively. PAC and all PAC/MONPs nanocomposites worked as mixed-kind inhibitors and their adsorption on the C-steel interface followed the isotherm Langmuir model. The findings were reinforced by FT-IR, FE-SEM and EDX analyses.

“…Excellent fitting of the experimental values was obtained following the simplest Langmuir monolayer adsorption mode where equivalency of all the adsorption sites is considered (correlation coefficient, R 2 = 0.995). According to this model, the degree of surface coverage θ (θ = η R %/100) is related to the concentration of the inhibitor (C) due to the following equation [15,16]:…”

Steel Corrosion Inhibition by Microbial Polysaccharide and Tartrate Mixture

et al. 2021

The objective of this study was to investigate steel corrosion inhibition by a mixture of microbial polysaccharide xanthan gum (XG) and potassium sodium tartrate (PST). It was established carbon steel corrosion inhibition by XG and PST in 3% NaCl solution using electrochemical methods and weight loss measurements. The efficiency of steel corrosion inhibition by xanthan gum significantly increases in the mixture with tartrate. The results of electrochemical impedance spectroscopy indicate the formation of a protective adsorption layer on the steel surface. The adsorption of the inhibitor mixture on mild steel surface obeys Langmuir isotherm. The protective effect of a mixture of xanthan gum and tartrate in chloride solution is likely due to the formation of single or double complexes with iron cations by their molecules. The XG/PST mixture provides a degree of metal protection of over 90% in an environment with a high concentration of chlorides and can become a promising corrosion inhibitor to protect against corrosion of steel structures.

“…Upon having a proper inhibitor source, there is still uncertainty whether the inhibitor is suitable for industrial application. This is due to the biodegradability of natural inhibitors, which causes their performances to deteriorate at longer immersion time, especially after 120 h of usage [ 9 , 10 , 11 ]. Even though degradation is a positive feature from an environmental point of view, it is a huge drawback for implementing natural inhibitors in the industry.…”

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

et al. 2021

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.
