“…Recently, carbon-based materials with superhydrophobic and super-oleophilic properties have been used as adsorbents of oily particles due to their excellent properties, such as easy surface modification, the large number of sources for its synthesis, high surface area, high selectivity for crude oil, and highly developed pore structure [21,22]. A great variety of carbon-based materials have been employed in oil removal, such as sponges [23], films [24], fiber [25,26], graphenes [27], xerogels, activated carbon [22,28], carbon nanotubes [29], and microspheres [30]. Among those materials, activated carbons (AC) have been shown to have the greatest ability to remove oil from O/W emulsions.…”

This work focused on evaluating the adsorptive removal of crude oil using a nano-intermediate based on magnetite nanoparticles supported on activated carbon synthesized from spent coffee grounds and the subsequent catalytic oil decomposition to recover by-products and regenerate the support material. The magnetite nanoparticles were synthesized by the co-precipitation method and were used as active phases on prepared activated carbon. The amount of crude oil adsorbed was determined by adsorption isotherms. In addition, dynamic tests were performed on a packed bed to evaluate the efficiency of the removal process. Thermogravimetric analysis and mass spectrometry were used to evaluate the catalytic powder and the quantification of by-products. Contrasting the results with commercial carbon, the one synthesized from the coffee residue showed a greater affinity for the oil. Likewise, the adsorption capacity increased by doping activated carbon with magnetite nanoparticles, obtaining an efficiency greater than 10%. The crude oil decomposition was carried out successfully by thermal cracking, obtaining a 100% removal. The gas produced after decomposition contains light hydrocarbons such as C2H4 and CH4 and shows a decrease in polluting species such as CO and CO2, leading to greater environmental sustainability of the process.

“…Oil spills can lead to water surfaces covered with oil and inhibit sunlight and oxygen entering the aquatic ecosystem. It can worsen because the oil layer on the water surface will spread due to the waves and wind 2) . One of the highly efficient methods to remove oil spills is adsorption using various adsorbent materials 3) .…”

Activated carbon-Fe3O4 composite was successfully synthesized. This work aimed to synthesize magnetic activated carbon and study its performance as a gasoline adsorbent. Dried coconut shells were pyrolyzed using a microwave to produce activated carbon (AC). The activated carbon-Fe3O4 composite was synthesized by the co-precipitation method, resulting in AC-M. Contact angles of AC-M with three different kinds of liquid were calculated using Drop Analysis LB-ADSA plugin in the ImageJ application program. Contact angles between AC-M with water, gasoline-water mixture, and gasoline were 84.156 ˚, 72.928 ˚, and 0 ˚, respectively. The contact angles show the hydrophobic properties of the composite. The adsorption capacity of AC-M for gasoline adsorption was 1252.22 mg/g for adsorption time 4 min and mass of adsorbent 0.09 g and followed the adsorption kinetic pseudo-second-order model from Ho and McKay with adsorption rate constant 0.0012 g/mg/min.

“…The systematic use of polymer membranes is mainly due to their main characteristics such as: energy e ciency, easy preparation, selectivity, low-cost, high mechanical resistance, eco-friendly, and recyclability [2][3][4]. In this way, membrane technology has been applied in the most different research front, such as gas separation [2,[5][6][7], CO 2 [8,9], heavy crude oil [10], metal [11][12][13], and organic compounds removal [14][15][16][17], catalysis [18,19], fuel cell [20][21][22][23], distillation processes [24][25][26], drug release [27][28][29], among other applications.…”

Polycyclic aromatic hydrocarbons (PAHs) are one of the most recalcitrant pollutant originated from the burning of coal, petroleum, and other fossil fuels. The human exposure to PAHs may contribute to develop several carcinogenesis mechanisms. The aim of the present study was to develop a mixed matrix membrane (MMM) based on polyethersulfone (PES) and functionalized mesoporous material for the remediation of PAHs mixture by adsorption processes. MCM-41-based mesoparticles were obtained from biomass reuse of rice husk ash (RHA) and functionalized with p-aminobenzoic acid (PABA). The hydrothermal and casting methods were effective and sustainable in the preparation of PABA-MCM-41 and PES-based MMMs, respectively. PES-based MMMs presented an excellent distribution of the arrays incorporated and small-angle ordering. The absorption of PAHs was in uenced by the incorporation of PABA-MCM-41 within the PES matrix.
