“…In the literature, the inhibiting properties in acid medium of ILs with imidazolium, , pyridinium, , ammonium, − pyridazinium, , and sulfonium − cations have been reported. These last compounds have been studied in sulfamic, phosphoric, and hydrochloric and sulfuric acids, reporting IE values from 84 to 98%.…”

The present work deals with the corrosion inhibition mechanism of API 5L X52 steel in 1 M H2SO4 employing the ionic liquid (IL) decyl(dimethyl)sulfonium iodide [DDMS+I–]. Such a mechanism was elicited by the polarization resistance (R p), potentiodynamic polarization (PDP), and electrochemical impedance spectroscopy (EIS) techniques, both in stationary and dynamic states. The electrochemical results indicated that the corrosion inhibition was controlled by a charge transfer process and that the IL behaved as a mixed-type corrosion inhibitor (CI) with anodic preference. The experimental results revealed maximal inhibition efficiency (IE) rates up to 93% at 150 ppm in the stationary state, whereas in turbulent flow, the IE fell to 65% due to the formation of microvortexes that promoted higher desorption of IL molecules from the surface. The Gibbs free energy of adsorption (ΔG°ads) value of −34.89 kJ mol–1, obtained through the Langmuir isotherm, indicated the formation of an IL monolayer on the metal surface by combining physisorption and chemisorption. The surface analysis techniques confirmed the presence of Fe x O y , FeOOH, and IL on the surface and showed that corrosion damage diminished in the presence of IL. Furthermore, the quantum chemistry calculations (DFT) indicated that the iodide anion hosted most of the highest occupied molecular orbital (HOMO), which eased its adsorption on the anodic sites, preventing the deposition of sulfate ions on the electrode surface.

“…In the literature, the linear correlation between the energy level of molecular orbitals and the effectiveness of various organic compounds (such as benzyl imidazole derivatives, amines, and others) as corrosion inhibitors is well known. [24][25][26] From Fig. 7, it can be seen that the E HOMO is located on the heteroatoms and the higher E HOMO value (−11.98 eV) indicate that the molecule has a tendency to donate electrons to appropriate acceptor molecules with low energy empty molecular orbital, which facilitates the adsorption of the inhibitor on the steel surface by affecting the electron transfer processes through the adsorbed layer.…”

“…In addition, the G7® disinfectant is the combination of glutaraldehyde and quaternary ammonium compounds that is strong and very effective complex but less powerful than Prophyl 2000® due to the quaternary ammonium compound, which is one of the disinfectants affected by the presence of organic matter (Battersby et al, 2017;Figueroa et al, 2017;Drauch et al, 2020). Additionally, the Pron-Tech® that contains dimethyl benzyl ammonium chloride compound within the QUATS family is probably one of the best chemicals to inhibit microbial germination by penetrating the bacterial cell membrane by electrostatic gravity to cause the internal substances to leak out, which eventually results in cell lysis and death (Abdel-Latef and Mohammed, 2021; Wang et al ., 2022).…”

“…The gram-positive bacteria are more sensitive to quaternary ammonium; this is due to the presence of more lipids on the cell wall (Battersby et al, 2017;Belter et al, 2022). Dimethyl benzyl ammonium chloride compound is among the earliest disinfectants within the QUATS family that have been widely used in various fields, such as food, medicine, oil field and industrial water treatment, owing to their broad antibacterial spectrum, good water solubility and environmental stability (Wang et al, 2022).…”

Proper management and hygiene are the keys for the poultry industry, profit mainly depends on efficient cleaning and disinfection. Disinfectants play an essential role in controlling pathogens in health care, animal production, and food-related industries. The effectiveness of a disinfectant is mainly dependent on the active compound chosen, its concentration, and the cleanliness of the surfaces to which it is applied. The purpose of this study was to evaluate the effectiveness of some disinfectants (Prophyl 2000®, G7®, Pron-Tech®, Alkadox®, and Biodine®) at different concentrations and contact times at 20, 40, 60, and 90 minutes against field isolated serotypes of E. coli, Pasteurella multocida, Campylobacter jejuni, and Staphylococcus aureus from chicken and duck farms production at a titer of 3×10 6 CFU (Colony Forming Unit) /cm 2 in the absence and presence of organic matter (O.M). The results showed that the efficiency of disinfectants was significantly increase with high concentration and long contact time. The Prophyl 2000® was the most powerful disinfectant against field pathogens, followed by G7®, Pron-Tech®, and Alkadox®, while Bio-dine® was the weakest disinfectant at the same conditions. Moreover, the organic matter hindered bactericidal power of many commercial disinfectants such as quaternary ammonium compounds (QUATS), halogen releasing agents including iodine, chlorine and its compounds, but some were not affected, such as glutaraldehyde. Finally, the success of the disinfection process in different poultry farms mainly depends on the selection of suitable disinfectants.
