“…Compared with surface roughness, wettability has a more significant effect on fouling deposition [12]. Moreover, another study showed that antifouling performance had much to do with the corrosion resistance of materials [13]. The crystal type and the growth rate of fouling could be affected by different types of corrosion.…”

This research aimed to investigate the effects of an ultrasonic surface rolling process (USRP) on the deposition behaviors in CaCO3 crystallization fouling for 304 stainless steel (304SS). The microstructure, surface morphology, and hydrophobic properties of the modified layer were characterized with optical microscopy, a roughness profile measurement instrument, and a contact angle measurement instrument. The corrosion and fouling behaviors of different surfaces were studied in simulated cooling water. The polarization curves and electrochemical impedance spectroscopy (EIS) were used to evaluate the electrochemical properties. The results showed that USRP-treated surfaces had better anti-corrosion and anti-fouling performance. The improvement in anti-fouling performance was attributed to the weakening of peaks and valleys, the reduction of surface defects, and the improvement of corrosion resistance.

“…The most common polymers are phosphonate, carboxylate, and sulfonate polymers. However, phosphonate and sulfonate polymers are being restricted due to environmental legislation [10][11][12]. With the increase of environmental awareness, environmentally friendly scale inhibitors have been drawing broad attention all over the world [13][14][15][16][17].…”

Polyaspartic acid (PASP)-based green scale inhibitor has great potential application in water treatment. Here, we first synthesized PASP in ionic liquid. Then, an effective PASP-based green scale inhibitor was synthesized by ring-opening graft modification of PASP with both aspartic acid (ASP) and monoethanolamine (MEA). Its chemical composition was characterized by gel chromatography (GPC), Fourier transform infrared spectroscopy (FTIR), and 1H nuclear magnetic resonance (1H NMR). Scale inhibition efficiency was measured by static scale inhibition tests. The results showed that the new PASP-based scale inhibitor has high scale inhibition to both CaCO3 and Ca3(PO4)2. When the concentration was increased to 2 mg/L, the inhibition efficiency of the new PASP-based scale inhibitor was 99% for CaCO3, while when the concentration was raised to only 4 mg/L, its inhibition efficiency increased to 100% for Ca3(PO4)2. Scanning electronic microscopy (SEM) and X-ray diffraction (XRD) were used to analyze the changes of crystal structure for CaCO3 and Ca3(PO4)2 after adding the new PASP-based scale inhibitor. The crystal size of CaCO3 and Ca3(PO4)2 became smaller and the crystal form became amorphous after adding the modified PASPs compared with adding pure PASP. Moreover, the modified PASP showed good biodegradation performance.

“…With the aim of clarifying the surfactant adsorption process on mineral surfaces, the traditional depletion measurements of static tests (batch equilibrium tests on crushed core grains) and dynamic tests (core flooding measurements) are often used to determine the adsorbed amounts of surfactants. − However, these methods cannot monitor the kinetic processes in real-time and cannot quantify the structure of the adsorbed surfactant layer. More recently, quartz crystal microbalance with dissipation (QCM-D) monitoring has been extensively applied to study the adsorption behavior of surfactants, allowing for the real-time quantitative analysis of adsorption and desorption processes onto model mineral surfaces with nanogram sensitivity. − Sensors covered with model minerals can be obtained commercially, , fabricated by covering with core-shell microparticles, , synthesized in bulk or prepared using different processing methodologies such as layer-by-layer deposition , and electrochemical techniques. − In the latter, the formed mineral deposit is a product of electrochemically assisted reactions (acid–base reaction), followed by the electrochemically controlled redox reaction. For example, electrochemical pH modulation allowing for the formation of CaCO 3 coating on stainless steel substrates and silica deposition derived from sol–gel processing .…”

Calcium Carbonate-Modified Surfaces by Electrocrystallization To Study Anionic Surfactant Adsorption

et al. 2021

In view of enhanced oil recovery, the adsorption behavior of surfactants is usually monitored on smooth model rock surfaces using quartz crystal microbalance with dissipation (QCM-D). However, this is an impractical situation as the effect of the surface roughness of reservoir rocks and its role in surfactant adsorption processes are not yet completely understood. The coupling of electrochemical techniques and QCM-D in one analysis setup (EQCM-D) provides a new methodology to explore complex surfactant adsorption processes. In this work, a uniform, rough, and well-covered model CaCO 3 surface was obtained on gold and platinum sensors to model carbonate rocks. This was achieved by the electrochemically formed hydroxide ions in the presence of bicarbonate and calcium ions, by which the controlled deposition of CaCO 3 resulted in sensor surface coverages in the range 35− 40%. Before using the deposited CaCO 3 surfaces, the adsorption of anionic surfactant alcohol alkoxy sulfate (AAS) on a smooth commercially available CaCO 3 surface was studied with varying CaCl 2 concentrations. For the first time, the structure and characteristics of the formed AAS layer were quantitatively described, indicating the formation of an incomplete bilayer. Compared to the smooth CaCO 3 surface, an increase in the frequency shift from 5 to 15 times was observed in sensors covered with rough CaCO 3 deposit. This observation was primarily attributed to the rougher surfaces that possess more adsorption sites for AAS binding and also to the effect of liquid trapping, inducing additional frequency shifts. The obtained results show that surfactant adsorption on rough surfaces was vastly different from that on smooth surfaces, and they provide a better understanding of the adsorption behavior of surfactants to mineral surfaces.
