A sewage sludge-based activated carbon (SBAC) intercalated MgAlFe ternary layered double hydroxide (SBAC-MgAlFe-LDH) composite was synthesized via the coprecipitation method. The adsorptive performance of the composite for phenol uptake from the aqueous phase was evaluated via the response surface methodology (RSM) modeling technique. The SBAC-MgAlFe-LDH phenol uptake capacity data were well-fitted to reduced RSM cubic model (R2 = 0.995, R2-adjusted = 0.993, R2-predicted = 0.959 and p-values < 0.05). The optimum phenol adsorption onto the SBAC-MgAlFe-LDH was achieved at 35 °C, 125 mg/L phenol, and pH 6. Under the optimal phenol uptake conditions, pseudo-first-order and Avrami fractional-order models provided a better representation of the phenol uptake kinetic data, while the equilibrium data models’ fitting follows the order; Liu > Langmuir > Redlich–Peterson > Freundlich > Temkin. The phenol uptake mechanism was endothermic in nature and predominantly via a physisorption process (ΔG° = −5.33 to −5.77 kJ/mol) with the involvement of π–π interactions between the phenol molecules and the functionalities on the SBAC-LDH surface. The maximum uptake capacity (216.76 mg/g) of SBAC-MgAlFe-LDH was much higher than many other SBAC-based adsorbents. The improved uptake capacity of SBAC-LDH was attributed to the effective synergetic influence of SBAC-MgAlFe-LDH, which yielded abundant functionalized surface groups that favored higher aqueous phase uptake of phenol molecules. This study showcases the potential of SBAC-MgAlFe-LDH as an effective adsorbent material for remediation of phenolic wastewater

This study reports the synthesis of date palm waste-derived biochar (B) supported Cu-Fe layered double hydroxides (CuFe LDH) composite by facile co-precipitation method. The adsorption performance of B-CuFe composite was evaluated for the removal of Eriochrome black T (EBT), as a model anionic azo dye, from the aqueous phase. The B-CuFe composites were characterized by FTIR, XRD, TGA, SEM-EDX and BET technique. Characterization results revealed the synergistic effect of biochar and CuFe-LDH has resulted in substantial improvement in physicochemical characteristics (i.e. surface functionality, surface area and surface morphology) of B-CuFe composite, which promotes rapid and improved adsorption of (EBT) from the solution. The B-CuFe composite with 2.5 g loading of biochar onto CuFe LDH layers showed better adsorption performance than that of other B-CuFe composites The adsorption process of EBT onto B-CuFe composite was well described by the RSM models (with R2=0.964-0.999). Acidic pH (2-5) and higher temperature favored the adsorption of EBT onto B-CuFe composite, and almost (70%–85%) of EBT was removed from the water within the first 15 min. The highest adsorption capacity, 565.32 mg/g of EBT onto B-CuFe composite, was obtained at pH 2.5 and 45 °C. The adsorption mechanism associated with the strong electrostatic and chemical interactions of EBT sulfonated anions (SO3−) with protonated hydroxyl surface groups (-OH2+) of B-CuFe composite. The B-CuFe composite exhibited better EBT removal in the presence of co-existing anions and demonstrated excellent reusability performance (11 % reduction) after five successive cycles. The results demonstrated that the B-CuFe composite showed great potential as a sustainable and cost-effective adsorbent for the purification of dye contaminated water bodies.

A wide range of emerging contaminants (ECs), such as pharmaceutically active compounds, personal care products (PCPs), endocrine-disrupting compounds (EDCs), and hormones are released into hospital wastewater (HWW). These contaminants can enter into natural environments, such as aquatic and terrestrial ones, thereby threatening human health and aquatic life. Conventional wastewater treatment plants are not designed to treat all types of chemical and biological contaminants, thereby allowing the release of these contaminants into water bodies, such as rivers, streams, and groundwater. Accordingly, adequate measures and advanced technologies should be implemented to prevent the discharge of ECs into aquatic environments. Reducing environmental health risks of HWW is particularly important amid the persistence of the COVID-19 pandemic. Although the necessary guidelines and legislation for wastewater treatment are available, efficient removal of ECs from HWW requires the applications of advanced treatment technologies. This paper provides a comprehensive review of the existing healthcare structures, ECs pathways to the environment, management practices, and effective treatment options for removing ECs from HWW. A critical evaluation of the current research advances, knowledge gaps, and directions for future research is also presented.

Polycyclic aromatic hydrocarbons are hazardous environmental pollutants that possess mutagenic and carcinogenic properties. Generally, the concentrations of PAHs in environmental water samples are very low, and it is challenging to detect such levels directly by the analytical instrumentation. Thus, the extraction of PAHs using suitable extraction methodology is required for sample cleanup and analyte enrichment. Dispersive solid-phase extraction has several advantages over conventional approaches for the extraction of PAHs from environmental water samples. In this article, we critically evaluate the role of different nano and micro sorbent materials employed in the extraction of PAHs. Carbon-based nanomaterials, metal-organic frameworks, polymeric nanocomposites, ionic-liquid based composites, and silica-based materials are explicitly covered. This review also provides insight on functional components of all types of sorbents and their way of interaction with PAHs. The factors affecting the dispersive (micro) solid phase extraction of PAHs such as the design of the sorbent, the ratio of functional material to magnetic core, sample volume, amount of sorbent, extraction and desorption times, desorption solvent and its volume, salt addition, and sample pH are critically appraised. Finally, a brief account on the accomplishments, limitations, and challenges associated with such methods is provided.

A first study on the adsorptive removal of tungsten species from the aqueous phase by using the multi-walled carbon nanotubes (MWCNTs) is reported. The MWCNTs were employed for the uptake of tungsten species at pH 6 in batch experiments. It was observed that 100% of tungsten species were removed in 2 h, by employing 75 mg of MWCNTs from the aqueous solution containing 10 ppm of tungsten. Adsorption equilibrium data were fitted by the three isotherm models namely the Langmuir, Freundlich, and Sips isotherms and best described by a three-parameter Sips model. The maximum experimental adsorption capacity of MWCNTs for tungsten was 17.64 mg/g, while the adsorption capacity anticipated by the Langmuir and Sips isotherm models was 20.58 and 25.18 mg/g, respectively. The adsorption kinetic data was adequately fitted by a pseudo-second-order model. Our present findings ascertained that MWCNTs could be a potential adsorbent for the removal of tungsten species from the aqueous phase.

In this study, wet impregnation technique was employed to impregnate the multi wall carbon nanotubes (MWCNTs) with different amounts of alumina (Al2O3) and manganese dioxide (MnO2). Raw and synthesized nanocomposites were characterized to study the surface texture, thermal stability, porosity, mineralogy and surface functional groups of materials using scanning electron microscopy (SEM), thermogravimetric analysis (TGA), N2 physisorption, X-ray diffraction (XRD), Fourier transform infrared (FTIR) and RAMAN spectroscopy. SEM micrographs and XRD diffractograms revealed that the Al2O3 and MnO2 had good dispersion on the MWCNTs surface. Thermal analysis demonstrated that presence of metallic constituents catalyse the oxidation of carbon and decreases the value of initial decomposition temperature of raw MWCNTs. Surface area and porosity were get reduced by impregnating MWCNTs with metals oxides due to coverage of outer surface of substrate with metal oxide nanoparticles. Application of synthesized nanocomposites showed almost 15% higher removal efficiency for removal of phenol from aqueous phases as compared to raw MWCNTs. These results indicate that this nanocomposite can be used for environmental remediation applications.

The wet air oxidation of benzene in the presence of phenol has been studied in an autoclave with a working volume of 1.24 L in the operating temperature range of 160-220oC at 1.72 MPa oxygen partial pressure. The initial benzene concentration was kept constant at 5.63 mmol/L, while the phenol concentration was varied from 0 to 200 mg/L and 100% excess of oxygen was used. The effect of temperature and phenol concentration was studied on the oxidation of benzene at pH 6. The addition of phenol to the system has significantly enhanced the degradation of benzene. The benzene oxidation was found to increase with an increase in the concentration of phenol. However, the rate of benzene degradation remains constant after the optimum concentration of phenol is reached. Benzene degradation increased with a rise in temperature. It was found that 100% degradation of benzene (5.63 mmol/L) was achieved in 30 minutes at pH 6, temperature of 200oC and 1.72 MPa oxygen partial pressure in the presence of phenol (25 mg/L) and 100% excess O2. It was concluded that the degradation of benzene proceeds in two stages and the activation energy was calculated to be 21.1 KJ/mol and 1.2*102 KJ/mol for the fast and slow step, respectively.
