“…It has oxidation states ranging from + 1 to + 5, however, it is most typically found in the + 4 as tetravalent vanadyl (VO 2 + ) and in the + 5 states as pentavalent vanadate (HVO 2− 4 , VO − 3 and/or H 2 VO − 4 ) species in natural and biological systems [3,4]. Vanadium may be found in 65 various minerals, including carnotite, vanadinite, and patronite that regarded as an important source of vanadium [5].…”

A considerable increase in the importance of vanadium globally and its common uses in many manufacturable alloys made it a target for much scientific research interested in extraction and recovery. A solid modified cellulose sorbent (GCIHQ) was prepared by simple grafting of cellulose, then immobilized with hydroxyquinoline, and examined as a sorbent for V(V) ions. FT-IR, TGA, BET, and SEM–EDX investigations were used to characterize the GCIHQ. A higher surface area for the synthesized GCIHQ resin has been recorded (65.8 m2/g) more than the used cellulose (21.7m2/g). Several vanadium sorption parameters using the modified GCIHQ from the sulfate medium were optimized namely contact time, pH, initial vanadium ions concentration, sorbent dose, and sorption temperature. The kinetics results revealed that the sorption of vanadium ions upon the synthesized sorbent followed the pseudo-second-order with R2 of > 0.99, which indicated that the sorption mechanism was chemical interaction. The sorption process was studied using Freundlich, Langmuir, Dubinin–Radushkevich, and Temkin isotherm models to describe the adsorbent-adsorbate interaction. The Langmuir model was the most fitting model with the experimental results; the experimental adsorption uptake of 113 mg/g was matched with that of the calculated results. The activation energy (Ea) for adsorption was 12.91 kJ.mol−1, indicating the process is to be chemisorption. Thermodynamic characteristics with ΔH of 13.46 kJ/mol and a ΔS 115.15 J/mol.K revealed the endothermic and spontaneous nature.

Removing contaminated Arsenazo III dye from contaminated effluent is a challenge and of great interest due to its hazard and environmental impact. Therefore, the biggest challenge was producing highly efficient, easy to recycle, and economically inexpensive adsorbent materials for the contaminated dye. Three chemically stable zirconium nanocomposites with unique properties were synthesized by gel-precipitation technology. The composition, chemical, and physical properties of zirconium molybdate, tungstate, and silicate nanocomposites have been extensively proven using many different and appropriate devices such as XRD, SEM–EDX, TEM, FT-IR, BET, DLS, TGA-DTA, and zeta potential. By utilizing the most effective adsorption techniques, Azo-dye was successfully bound to ZrMo-NPs, ZrW-NPs, and ZrSi-NPs composites. The uptake capacities for these composites were measured at 0.29, 0.79, and 1.61 mmol.g−1, respectively. The sorption parameters were optimized as follows: a feed solution pH of 3 for ZrMo-NPs, a pH of 2.3 for ZrW-NPs, and a pH of 2.3 for ZrSi-NPs. The stirring time was set at 30 min, the metal ion concentration was 1.64 mmol L−1, and the sorbent dose was 7.5 mg. The adsorption results agreed well with the Langmuir isotherm and the pseudo-second-order reaction models and demonstrated the endothermic nature and kinetic improvement by increasing temperatures. The three nanocomposites effectively eliminated tainted dye from lab wastewater, offering promise for their potential applications in the future. Graphical Abstract
