“…5a clearly reveals only one capacitive loop in the Nyquist plots, which could be attributed to a single charge transfer. 44 Meanwhile, the size of these loops increases with the rise of ER concentration up to 10 À3 mol L À1 , which signies that ER was adsorbed on the carbon steel surface, and the area exposed to the corrosive 1 M HCl solution was reduced. The electrochemical equivalent circuit used to model the experimental data is depicted in Fig.…”

“…At higher concentrations, the adsorption of surfactant occurs perpendicularly until the surface is completely saturated with the surfactant. The biocidal effect of the SCGS was credited to the effect of its structure, two quaternary nitrogen atoms (R 4 N + ) at the cathodic site, and two counter ions (Br − ), the π-electrons of two pyridine rings, and two azomethine (-CH=N-) groups at the anodic site [7][8][9][44][45][46][47].…”

“…The activity of cationic gemini surfactants against microorganisms in bulk phases and on surfaces (biofilms) generally depends on their structures [6]. The antimicrobial activity in the bulk phases mainly depends on two quaternary nitrogen atoms (R 4 N + ), alky-chain lengths, counter ions, spacer structures, and the effect of additive functional groups, such as pyridine rings and azomethine [5,[7][8][9]. The hypothesized antimicrobial activity mechanism of cationic gemini surfactants was attributed to the electrostatic interaction between the surfactant cationic group (R 4 N + ) and the negatively charged group of the plasma membrane (lipoprotein) of bacteria.…”

The Egyptian petroleum industries are incurring severe problems with corrosion, particularly corrosion that is induced by sulfidogenic microbial activities in harsh salinity environments despite extensively using biocides and metal corrosion inhibitors. Therefore, in this study, a synthesized cationic gemini surfactant (SCGS) was tested as a broad-spectrum antimicrobial, anti-bacterial, anti-candida, anti-fungal, anti-biofilm (anti-adhesive), and bio-dispersion agent. The SCGS was evaluated as a biocide against environmental sulfidogenic-bacteria and as a corrosion inhibitor for a high salinity cultivated medium. The SCGS displayed wide spectrum antimicrobial activity with minimum bactericidal/fungicidal inhibitory concentrations. The SCGS demonstrated anti-bacterial, anti-biofilm, and bio-dispersion activity. The SCGS exhibited bactericidal activity against environmental sulfidogenic bacteria and the highest corrosion inhibition efficiency of 93.8% at 5 mM. Additionally, the SCGS demonstrated bio-dispersion activity against the environmental sulfidogenic bacteria at 5.49% salinity. In conclusion, this study provides a novel synthesized cationic surfactant with many applications in the oil and gas industry: as broad-spectrum antimicrobial and anti-biofilm agents, corrosion inhibition for high salinity, biocides for environmentally sulfidogenic bacteria, and as bio-dispersion agents.

The brown algae Cystoseira Baccata extract as a friendly corrosion inhibitor on carbon steel in acidic media

The inhibition properties of the isopropanol extract of brown seaweed Cystoseira baccata (CBE), against corrosion of carbon steel in HCl 1M medium, was evaluated using the weight-loss method and electrochemical measurements. It was shown that the extract exhibit excellent performance as inhibitors and the inhibition efficiency increased with the concentration. The maximal value of inhibition efficiency is 86.5% obtained by the Tafel method at 700 mg/l at 298 K. The polarization curves indicate that the CBE acts as a mixed-type inhibitor. The results obtained by electrochemical impedance spectroscopy shows that the inhibitory action of this extract is based on the increase in the charge transfer resistance and the decrease in the double layer capacity. The temperature influence studied in the temperature range 298-328 K by weight-loss method shows that the inhibition efficiency decreases with increasing temperature for all concentrations of CBE. The adsorption and activation parameters allow us to suggest the physical adsorption of this inhibitor on the metal. The adsorption of the extract on the carbon steel follows Langmuir adsorption isotherm.
