“…Industrial wastewater is treated with different methods based on its physical, chemical, and biological properties. The most famous methods for treating water are floatation, coagulation/flocculation, sedimentation, filtration, disinfection, sludge drying, fluoridation, pH correction, and adsorption. ,− Among these methods, adsorption is the most cost-effective technology for the treatment and refinement of wastewater, groundwater, and industrial effluents. − This process can be an acceptable low-cost solution for the purification of water. − Adsorption is more applicable than membrane filtration, especially when treating large quantities of industrial effluent, which makes it difficult to apply the membrane process at an industrial scale. ,− Carbon, silica, and metal oxide-based materials are the most efficient adsorbent materials. − Awual has developed N , N -disalicylidene-4,5-dimethyl-phenylenedene ligand-impregnated mesoporous silica nanocomposite mercury(II) uptake from wastewater .

Wastewater treatment for the removal of heavy metals can reduce environmental contamination, enable safer industrial activities, and enhance sustainable practices. Efficient materials processing oriented to low temperature operating conditions; thus, the development and modeling of carbon nanotube/SDS-alumina nanocomposite-based adsorbents (CNT/ SDS-alumina) for efficient wastewater treatment are investigated in this work. The optimization of a low temperature-based process is targeted in this work to achieve a cost-effective method for fabrication of CNT/SDSalumina nanocomposites. The fabrication process involves the investigation of various heating conditions in an oven and autoclave with successful optimization for the formation of porous CNT/SDS-alumina nanocomposite-based adsorbents. The fabricated materials were characterized by TEM, SEM, XRD, FTIR, and surface area analysis. The results indicate that the heating condition is the factor controlling the formation of the porous structure of the CNT/SDS-alumina nanocomposite, which affects the wastewater treatment application. The surface area was higher (49.26−51.02 cm 2 /g) for CNT/SDS-alumina nanocomposite-based adsorbents prepared under autoclave heating conditions. The best adsorption capacity values obtained using the CNT/SDS-alumina nanocomposite prepared under autoclave conditions were 463 mg/g for arsenic ions and 418 mg/g for mercury ions, revealing the high efficiency of the prepared materials for the adsorption of pollutants. The adsorption process for the removal of arsenic and mercury is reported to follow the second-order kinetic model. The adsorption data for the CNT/SDS-alumina nanocomposite-based adsorbents prepared under autoclave heating conditions are well fitted with the Langmuir isotherm, suggesting a monolayer adsorption mechanism. Additionally, the prepared CNT/SDS-alumina nanocomposite-based adsorbents are recommended for potential applications involving the adsorption of various heavy metals for real wastewater treatment situations.

“…The bonding nature and functional groups present in the CdO@PPy electrocatalyst were characterized by FTIR and are illustrated in Figure b. The principal peak at 3400 cm –1 confirms the presence of the −OH vibration bond due to the moisture content absorbed by the as-synthesized material. , Additionally, the peak at 1174.89 cm –1 corresponds to the carbon and oxygen bond (C–O) and the absorption band at 1025.71 cm –1 corresponds to the CN bond present in polypyrrole nanotubes. Most importantly, the band at 570.28 cm –1 is the characteristic peak of the cadmium (Cd) and oxygen stretching in cadmium oxide nanoparticles .…”

In the realm of electrochemical sensor application, the development and fabrication of semiconducting metal oxides with the integration of conducting polymers for the trace-level detection of pharmaceutical medicines garnered considerable interest. Herein, we reported facile cadmium oxide decorated with polypyrrole nanotubes fabricated on a glassy carbon electrode (CdO@PPy/GCE) for efficient determination of antihistamine drug promethazine hydrochloride (PMH). The as-synthesized CdO@PPy composite was characterized by various analytical tools like X-ray powder diffraction, Fourier transform infrared spectroscopy, Raman spectroscopy, scanning electron microscopy, and X-ray photoelectron spectroscopy. Furthermore, the electrocatalytic activity of the modified electrode for PMH detection was examined by voltammetry and amperometric methods, and the modified electrode exhibited lower charge transfer resistance compared to the bare GCE. Under the optimized condition, the fabricated electrode shows a wide linear range (50−550 μM), better sensitivity (0.13 μAμM −1 cm −2 ), low detection limit (10.83 nM) (S/N = 3), and excellent selectivity and reproducibility toward PMH detection. Moreover, the modified GCE depicted eminent practical ability for PMH detection in lake water and pharmaceutical tablets.

“…Due to this, sometimes, MPs can be considered as a bioremediation strategy to eliminate contaminants present in the aqueous medium, in the same way composite materials are used to remove organic pollutants from aqueous media. For instance, cotton fiber covered with chitosan [10], the functional organic ligand of 4-tert-Octyl-4-((phenyl)diazenyl)phenol (TPDP) with mesoporous silica [11] and the chemical ligand of N,N-bis(salicylidene)1,2-bis(2-aminophenylthio)ethane (BSBAE) also with mesoporous silica [12] have shown high removal of Remazol Brilliant Red F3B (RR), copper (II) and cadmium (II), respectively. However, if the biota ingests MP with pollutants, they can introduce toxic compounds into the trophic chain, leading to chemical, ecological, and biological alterations in species and ecosystems [5,13], leading to bioaccumulation in organisms [14].…”

Sorption of Total Petroleum Hydrocarbons in Microplastics

As is the case for many others in the world, Mexican seas face complex pollution challenges; two of the contaminants that require special attention for their prevalence, possible chemical interactions, and relation to the country’s economy are leaked petroleum and microplastics (MP). This research assessed the sorption of total petroleum hydrocarbons (TPH) as fuel oil on microplastics in laboratory and field scenarios. Preliminary tests allowed the development and validation of a methodology to measure the sorbed fuel oil by Soxhlet extraction, with a 99.65% recovery rate. The amount of TPH sorbed in the lab followed the order LDPE > PS > PP > PVC > PET > HDPE, with the highest concentration found on LDPE. The sorption of fuel oil on microplastics is correlated to the surface area of the plastic particles and could also be related to the crystallinity of plastics. Sorption, for all plastics, was consistent with a second-order kinetic model. The analysis of field samples collected on beaches of the Gulf of Mexico varied from 1660 to 35,258 mg/kg MP. It must be noticed that, unlike others, this research quantified a family of contaminants, which could explain the high concentrations observed on microplastics.
