“…It also governs the active surface charge and the functional group species present at the surface of the adsorbent [1, 2]. This assists the barium ions to not easily form complexes and hydrolyze [4]. In order to determine the effect of pH change on the removal activity and the optimal pH, this set of experiments has been conducted within a pH range 3–11 by using a fixed mass of adsorbent 10 mg in 25 mL barium solution.…”

“…Fard et al [3] prepared MXene by a ball mill process which exhibited adsorption capacity of 9.3 mg/g of Ba(II) within 120 min at pH 6. Majidnia et al [4] reported that maghemite and titania PVA-alginate beads prepared by a coprecipitation method showed adsorption capacity of 19.37 mg/g of Ba(II) for a contact time of 120 min. Ghaemi et al [24] suggested that the dolomite powder demonstrated low adsorption capacities of 1.172 mg/g and 3.958 mg/g with a contact time of 120 min at pH 5.5, respectively, for Sr (II) and Ba(II) removal from water.…”

The development of advanced materials for the removal of heavy metal ions is a never-ending quest of environmental remediation. In this study, a facile and cost-effective approach was employed to synthesize copper ferrite (CF) and copper ferrite/reduced graphene oxide (CG) by microwave assisted combustion method for potential removal of barium ions from aqueous medium. The physiochemical characterizations indicated the formation of magnetic nanocomposite with an average crystallite size of CF and CG is 32.4 and 30.3 nm and with specific surface area of 0.66 and 5.74 m 2 /g. The magnetic results possess multidomain microstructures with saturation magnetization of 37.11 and 33.84 emu/g for CF and CG. The adsorption studies prove that upon addition of rGO on the spherical spinel ferrite, the adsorption performance was greatly improved for CG nanocomposite when compared with the bare CF nanoparticles. The proposed magnetic adsorbent demonstrated a relatively high Ba 2+ adsorption capacity of 161.6 mg•g -1 for CG nanocomposite when compared to 86.6 mg•g -1 for CF nanoparticles under optimum conditions (pH = 7 ; T = 25 °C). The pseudo-first-order (PFO), pseudo-second-order (PSO), and Elovich models were fitted to the kinetic data, the yielded R 2 value of 0.9993 (PSO) for CF and 0.9994 (PSO) for CG which is greater than the other two models, which signify that the adsorption process is chemisorption. Thermodynamic studies show that barium adsorption using CF and CG adsorbents is endothermic. The as-fabricated CuFe 2 O 4 /rGO nanocomposite represents a propitious candidate for the removal of heavy metal ions from aqueous solutions.

“…This approach is particularly of interest in this review as it relies on TiO 2 for barium ion reduction. Although this approach was able to achieve a 50% reduction in barium ion concentration after 120 min, using anatase, the photocatalytic effect can be optimized to remove barium ions (99%) [92]. Therefore, the integration of photocatalytic principles of anatase into the design of MXene compounds may yield effective results.…”

Efficient approaches for toxic metal removal from wastewater have had transformative impacts to mitigating freshwater scarcity. Adsorption is among the most promising purification techniques due to its simplicity, low cost, and high removal efficiency at ambient conditions. MXene-based nanoarchitectures emerged as promising adsorbents in a plethora of toxic metal removal applications. This was due to the unique hydrophilicity, high surface area, activated metallic hydroxide sites, electron-richness, and massive adsorption capacity of MXene. Given the continual progress in the rational design of MXene nanostructures for water treatment, timely updates on this field are required that deeply emphasize toxic metal removal, including fabrication routes and characterization strategies of the merits, advantages, and limitations of MXenes for the adsorption of toxic metals (i.e., Pb, Cu, Zn, and Cr). This is in addition to the fundamentals and the adsorption mechanism tailored by the shape and composition of MXene based on some representative paradigms. Finally, the limitations of MXenes and their potential future research perspectives for wastewater treatment are also discussed. This review may trigger scientists to develop novel MXene-based nanoarchitectures with well-defined shapes, compositions, and physiochemical merits for efficient, practical removal of toxic metals from wastewater.

“…Thus, the PVA-boric acid method has been introduced to combine with sodium alginate (SA) to provide resiliency and a higher modulus. 23 The PVA/SA-based interpenetrating polymer network (IPN) hydrogels have also been reinforced by graphene oxide, 24 chitosan, 25 maghemite and titania nanoparticles, 26 clay, 27 and polyacrylamide 28 for dye or heavy metal removal. However, a lignosulfonate-based multipore 3D biocomposite adsorbent has not been studied yet, which is expected to significantly improve iron adsorption in contaminated water and be recycled safely as micronutrients for plant growth.…”

The essential nutrients (e.g., iron) for food production are nonrenewable resources, which cannot satisfy the need of a fast-growing global population. Meanwhile, excessive irons accumulated in iron-rich water pose an adverse effect on human and ecosystem health. Thus, it is necessary to develop a cost-effective and eco-friendly adsorbent for reclaiming irons from iron-accumulated water and which cannot satisfy the need of a fast-growing global population. Meanwhile, excessive irons accumulated in iron-rich water pose an adverse effect on human and ecosystem health. Thus, it is necessary to develop a cost-effective and eco-friendly adsorbent for reclaiming irons from iron-accumulated water and these irons for growing crops. In this study, a simple gelation–solidification process aided by phase separation is developed to fabricate a biodegradable alginate/polyvinyl alcohol/lignosulfonate (SA/PVA/LS) three-dimensional (3D) biocomposite adsorbent. Calcium chloride and boric acid are used as cross-linkers between polymers with hydroxyl groups. This bioadsorbent owns a multiporous architecture, ample functional groups, and enhanced total pore volume. A multilayer adsorption mechanism endows it with a high iron adsorption capacity (52 mg/g) via Langmuir simulation and a physiochemical adsorption mechanism. The porous 3D structure of the biocomposite could be observed from SEM and CT scanning. After iron loading, it can be applied as an excellent substitute for a commercial EDTA-Fe micronutrient to promote plant growth with a comparable ratio of root to shoot length. This eco-friendly, highly efficient, and filled 3D bioadsorbent is expected to open a door to achieving circular recovery of plant essential plant nutrients from waste resources for crop production.
