“…While the Bode plot in the presence of 100 mg L À1 QB has a broadening capacitive loop, which can be attributed to the superposition of two time constants that cannot be significantly distinguished. This result indicates that the adsorption of QB on the surface of mild steel is defective and local corrosion appears on the steel surface [40,41].…”

“…In the presence of a templating agent, thin films with superior porosity characteristics can be formed . Phenomenologically similar is the formation of calcite, which can be precipitated upon electrochemical pH modulation. − Electrochemistry can not only be used for model mineral deposition, but also to study the interfacial properties, such as charge transfer resistance, dielectric properties, or coverage estimation.…”

The ability to study the adsorption behavior of surfactant species is of interest in the field of enhanced oil recovery (EOR), especially pertaining to alkaline surfactant flooding. In this work, a calcite model mineral surface was obtained by electrochemically assisted deposition. This was achieved via the nitrate and/or oxygen electroreduction reactions in the presence of bicarbonate and calcium ions, by which controlled deposition of calcium carbonate was effected on a quartz crystal microbalance sensor covered with an electroactive gold layer. In addition, the effect of pH and Ca 2+ concentration on the effective surface charge of the deposited calcite particles was mapped. Calcite-modified sensors were used in conjunction with a quartz crystal microbalance with dissipation monitoring to study the effect of Na + and Ca 2+ concentration on the adsorption behavior of an anionic alcohol alkoxy sulfate (AAS) surfactant. Adsorption of the surfactant remained indifferent to ionic concentrations around the isoelectric point of calcite. Still, electrostatics play an important role in this regard, and it is essential to decrease the Ca 2+ concentration sufficiently to minimize AAS adsorption. The results from this study show that a relatively simple method allows for the controlled deposition of a model rock surface, and there is ample opportunity to extend the work to other metal oxide surface types, including complex mixtures as can be obtained by co-deposition. Furthermore, the findings from these adsorption studies aid in the determination of optimal flooding parameters, with the aim to increase the efficiency and efficacy of EOR.

“…A more precise technique, electrocrystallization, applies electrochemical measurements [18][19][20][21][22][23][24][25][26][27][28][29]. A working electrode, which is usually made of steel, is polarized cathodically to a potential of 1.1 V/SCE to cause oxygen reduction.…”

A new electrode to study both scaling and corrosion processes of mild steel in tap water was developed. Two identical steel rings are placed on the outside of a glass tube which is heated from inside with an electric spiral; the rings are connected to a corrometer to form a two-electrode corrosion probe. The corrosion rate variations with scale thickness, scale deposition time, and solution composition are measured using the linear polarization resistance technique. The deposited scale was formed of calcite crystals of 50–100 μm as established with SEM and XRD. The scale layer of 0.2 mm formed in tap water within 90 hours reduces the steel corrosion rate from 0.8 to 0.1 mm/year and serves as a barrier layer to prevent further corrosion.
