“…There is currently a reborn interest in research of the synthesis, characterization, and applications of activated carbons, as shown by recent reviews and the high number of publications on this topic that can be found in the technical literature [19][20][21][22][23][24]. Activated carbons can be synthesized from any carbonaceous precursor, such as coal [25][26][27], discarded tires [28][29][30], lignin [31][32][33], or biomass waste [34][35][36][37], among others, preferably with low inorganic content. Nowadays, most of the research is focused in the synthesis of activated carbons from biomass waste due to some unquestionable advantages: (1) this process results in the revalorization of waste, (2) the synthesized activated carbons have a lower cost since they are produced from low economic value precursors, (3) they are obtained from renewable resources, and (4) after their lifetime, the combustion of these activated carbons does not increase CO 2 accumulation in the atmosphere because this CO 2 has been previously captured during plant growth [38,39].…”

This study reviews the most relevant results on the synthesis, characterization, and applications of activated carbons obtained by novel chemical activation with FeCl3. The text includes a description of the activation mechanism, which compromises three different stages: (1) intense de-polymerization of the carbon precursor (up to 300 °C), (2) devolatilization and formation of the inner porosity (between 300 and 700 °C), and (3) dehydrogenation of the fixed carbon structure (>700 °C). Among the different synthesis conditions, the activation temperature, and, to a lesser extent, the impregnation ratio (i.e., mass ratio of FeCl3 to carbon precursor), are the most relevant parameters controlling the final properties of the resulting activated carbons. The characteristics of the carbons in terms of porosity, surface chemistry, and magnetic properties are analyzed in detail. These carbons showed a well-developed porous texture mainly in the micropore size range, an acidic surface with an abundance of oxygen surface groups, and a superparamagnetic character due to the presence of well-distributed iron species. These properties convert these carbons into promising candidates for different applications. They are widely analyzed as adsorbents in aqueous phase applications due to their porosity, surface acidity, and ease of separation. The presence of stable and well-distributed iron species on the carbons’ surface makes them promising catalysts for different applications. Finally, the presence of iron compounds has been shown to improve the graphitization degree and conductivity of the carbons; these are consequently being analyzed in energy storage applications.

“…Triton‐X 100 belongs to a non‐ionic surfactant produced by polymerization of octylphenol with ethylene oxide 2 . It finds its application in the electronic industry, 3 polymer industry as an emulsifier and stabilizer, 4 and as a surfactant in the petroleum industry 5 . Thus it ends up in water sources, causing pollution.…”

In the present article, nanocomposite TiO2/polysulfone membranes were prepared for advanced water treatment and removal of surfactant and dye from water were evaluated. The nanocomposite membranes demonstrated enhanced antifouling properties. Scanning electron microscopy, energy‐dispersive X‐ray spectroscopy, atomic force microscopy, and transmission electron microscopy were conducted to characterize particles and fabricated nanocomposite membranes. The antifouling characteristics of the membrane were assessed by ultrafiltration of model foulants such as sodium alginate and egg albumin and it was found that the nanocomposite membranes were less prone to fouling. Separation performance of Congo red dye and non‐ionic surfactant Triton X‐100 were evaluated and the nanocomposite membranes have shown encouraging results. With incorporation of TiO2 nanoparticles, ultimate tensile strength increased while elongation at break decreased. Decrement in pore size with incorporation of nanomaterial and change in surface characteristics were responsible for improved performance of membrane.

Performance evaluation of different types of surfactants to inhibit clay swelling during chemical enhanced oil recovery

In most cases, sandstone reservoirs contain clay particles. When a fluid with low salt content is injected into the reservoir, clay particles swell, and the rock's permeability decreases. Since surfactant flooding with water that has lower salinity than formation water is used to improve oil recovery, this study examines the swelling inhibitive strength of various surfactants. The study investigates the effect of surfactants on clay swelling inhibition through linear swelling and sedimentation experiments which showed that cetyl trimethyl ammonium bromide (CTAB) inhibits clay swelling. The optimum CTAB concentration was found to be 1 wt.%. However, sodium dodecyl sulphate (SDS) and Triton X‐100 (TX‐100) did not inhibit clay swelling. Sandpack experiments confirmed that CTAB prevented clay swelling and sandpack permeability reduction, while SDS and TX‐100 did not. The injection pressure results for the different surfactants were as follows: CTAB—39 psi, SDS—203 psi, TX‐100—223 psi, deionized water (DW)—324 psi, and KCl—78 psi. The mechanism of surfactant performance in affecting clay swelling was investigated based on thermal gravimetric analysis (TGA), zeta potential, and scanning electron microscope (SEM) images. The results showed that CTAB compensates for the surface charge of clays through a cation exchange mechanism. The amount of absorbed water for clays modified with CTAB was lower than that for other surfactants. The SEM images confirmed that the CTAB‐modified clays were larger and did not disintegrate during dispersion; however, in other cases, the particle size was smaller.
