“…Among a wide array of methods employed for the treatment of wastewater, adsorption has received many attentions since it is simple, cost‐effective, and reliable. Hence, seeking for effective adsorbents is increasingly enhancing because the majority of widely used adsorbent materials are very expensive, difficult to recover and recycle and also need high cost for activation and reactivation …”

In the present work, Mn‐doped CuO‐NPs‐AC was prepared by a simple method, characterized using various techniques such as FESEM, EDX, XRD, PSD, and pHpzc and finally used for the adsorption of malachite green (MG) and methyl orange (MO) in a number of single and binary solutions. A series of adsorption experiments were conducted to investigate and optimize the influence of various factors (such as different pH, concentration of MG and MO, adsorbent mass, and sonication time) on the simultaneous adsorption of MG and MO using response surface methodology. Under optimal conditions of pH 10, adsorbent dose of 0.02 g, MG concentration of 30 mg L−1, MO concentration of 30 mg L−1, and sonication time of 4.5 min at room temperature, the maximum predicted adsorption was observed to be 100.0%, for both MG and MO, showing that there is a favorable harmony between the experimental data and model predictions. The adsorption isotherm of MO and MG by Mn‐doped CuO‐NPs‐AC could be well clarified by the Langmuir model with maximum adsorption capacity of 320.69 mg g−1 and 290.11 mg g−1 in the single solution and 233.02 mg g−1 and 205.53 mg g−1 in the binary solution by 0.005 g of adsorbent mass for MG and MO, respectively. Kinetic studies also revealed that both MG and MO adsorption were better defined by the pseudo‐second order model for both solutions. In addition, the thermodynamic constant studies disclosed that the adsorption of MG and MO was likely to be influenced by a physisorption mechanism. Eventually, the reusability of the Mn‐doped CuO‐NPs‐AC after six times showed a reduction in the adsorption percentage of MG and MO.

“…However, these operations are often expensive, time consuming, and difficult to handle in comparison to adsorption. On the other hand, adsorption using different adsorbents‐agricultural wastes, activated carbons, carbon nanotubes, composite materials, is believed to be firmly efficient, affordable and extremely effective technique for the uptake of organic dyes from aqueous environment. However, most of these adsorbents suffer from lower adsorption efficiency, higher contact time for attaining equilibrium, slower kinetics of adsorption, separation difficulty from the fluid, and sometimes high capital cost.…”

NiFe 2 O 4 /polythiophene nanocomposite was synthesized by in situ chemical oxidative polymerization of thiophene in NiFe 2 O 4 nanoparticles presence, whereas NiFe 2 O 4 nanoparticles were prepared via coprecipitation method. Fourier transform infrared (FTIR), X-ray diffraction (XRD), UV-Visible, and SEM, EDX techniques were used for characterization of the nanocomposite. The effect of various parameters such as adsorbent dose, contact time, initial dye concentration, and initial pH of solution on the adsorption of Janus green B (JG) and Fuchsin basic (FB) onto the nanocomposite was optimized by batch studies. The equilibrium uptake data ascribed well to the Langmuir model with maximum adsorption capacity of 143 and 498 mg/g at 303 K for JG and FB, respectively. The exceptional high adsorption capacity of NiFe 2 O 4 /polythiophene nanocomposite for JG and FB was ascribed to π-π and electrostatic interactions. Kinetics studies pointed out that JG and FB removal followed pseudo-second order model. The negative values of ΔH (JG: -47.28; FB: −38.00 kJ/ mol) and ΔG (JG: −9.347 to −6.442; FB: −14.16 to -12.85 kJ/mol) pointed out the feasibility, spontaneity, and exothermic nature of removal process. Negative value of ΔS (JG: -0.125; FB: -0.078 kJ/mol) suggested decrease in randomness at the solid/ liquid interface. The results showed that NiFe 2 O 4 /polythiophene is an appealing adsorbent for the uptake of JG and FB dyes from aquatic environment.

“…Toluene, ethylbenzene and xylene were effectively adsorbed on the surface of functionalized multi-walled carbon nanotubes via hydrogen bonds and π-π interactions [ 137 ]. The sorption of six named dyes belonging to the indigoid, arylmethane and azo classes of dyes on Fe 3 O 4 @haemogloin were reported to be dominated by electrostatic interactions [ 12 ]. Adsorbed analytes are subsequently recovered by eluting with a suitable solvent ( Figure 6 ).…”

The demand for water is predicted to increase significantly over the coming decades; thus, there is a need to develop an inclusive wastewater decontaminator for the effective management and conservation of water. Magnetic oxide nanocomposites have great potentials as global and novel remediators for wastewater treatment, with robust environmental and economic gains. Environment-responsive nanocomposites would offer wide flexibility to harvest and utilize massive untapped natural energy sources to drive a green economy in tandem with the United Nations Sustainable Development Goals. Recent attempts to engineer smart magnetic oxide nanocomposites for wastewater treatment has been reported by several researchers. However, the magnetic properties of superparamagnetic nanocomposite materials and their adsorption properties nexus as fundamental to the design of recyclable nanomaterials are desirable for industrial application. The potentials of facile magnetic recovery, ease of functionalization, reusability, solar responsiveness, biocompatibility and ergonomic design promote the application of magnetic oxide nanocomposites in wastewater treatment. The review makes a holistic attempt to explore magnetic oxide nanocomposites for wastewater treatment; futuristic smart magnetic oxides as an elixir to global water scarcity is expounded. Desirable adsorption parameters and properties of magnetic oxides nanocomposites are explored while considering their fate in biological and environmental media.
