“…Nevertheless, the authors addressed the chelator’s affinity for Fe(III) ions throughout the extraction process 32 . Similar findings have been reported in the literature 28 , 33 – 36 . Consequently, advancing chelating agents specifically tailored for V(V) is necessary.…”

Recycling vanadium from alternative sources is essential due to its expanding demand, depletion in natural sources, and environmental issues with terrestrial mining. Here, we present a complexation-precipitation method to selectively recover pentavalent vanadium ions, V(V), from complex metal ion mixtures, using an acid-stable metal binding agent, the cyclic imidedioxime, naphthalimidedioxime (H2CIDIII). H2CIDIII showed high extraction capacity and fast binding towards V(V) with crystal structures showing a 1:1 M:L dimer, [V2(O)3(C12H6N3O2)2]2−, 1, and 1:2 M:L non-oxido, [V(C12H6N3O2)2] ̶ complex, 2. Complexation selectivity studies showed only 1 and 2 were anionic, allowing facile separation of the V(V) complexes by pH-controlled precipitation, removing the need for solid support. The tandem complexation-precipitation technique achieved high recovery selectivity for V(V) with a selectivity coefficient above 3 × 105 from synthetic mixed metal solutions and real oil sand tailings. Zebrafish toxicity assay confirmed the non-toxicity of 1 and 2, highlighting H2CIDIII’s potential for practical and large-scale V(V) recovery.

“…Noori et al 86 used a mixture of 0.25 M D2EHPA and 0.35 M Cyanex 272 to extract V( iv ) at pH 2.5 and extract Ni( ii ) at pH 5.5. Tang et al 87 illustrated the chemical behavior of V extraction from the aqueous leachate of stone coal. The authors reported that the extraction efficiency increases as the pH increases up to 2.5.…”

“…For example, Cyphos IL 101 has been successfully applied in solvent extraction for the recovery of nickel and cadmium from the “black mass” of spent Ni-Cd batteries (Mahandra et al 2022 ), gold from thiosulfate leachate of sulfidic gold ore (Paiva et al 2022 ), and platinum-group metals from spent auto-catalysts (Chen et al 2022b ). Cyphos IL 104 proved to be an efficient extractant in ionic liquid extraction of rare earth elements (REEs) (Lu et al 2022 ; Wiecka et al 2022 ) as well as platinum group metals (Tang et al 2022 ) from different types of leachates obtaining from waste (e.g., spent neodymium magnets, automotive converters). D2EHPA has been used, among others, in solvent extraction intended for vanadium removal from aqueous leachate of stone coal after low-temperature sulfation roasting and of indium recovery from acidic leaching solutions (Grigorieva et al 2022 ; Bensaadi et al 2022 ).…”

In this study, we present the results of the first comparison of the elimination of toxic Cr(VI) ions, which are hazardous contamination of the environment, from aqueous solutions using ion exchangers (IEs) and polymer materials (PMs) impregnated with D2EHPA or ionic liquids (Cyphos IL 101 and Cyphos IL 104). Sorption of Cr(VI) ions and desorption from the formulated sorption materials were carried out. In comparison, classical solvent extraction was accomplished. Fourier transform infrared-attenuated total reflectance spectroscopy (FTIR-ATR), scanning electron microscopy-energy dispersive spectroscopy (SEM-EDS), and atomic force microscopy (AFM) have been used for characterization of the structure of developed IEs and PMs. The highest efficiency of adsorption of Cr(VI) ions was obtained using PMs with ionic liquids (>82%). Desorption from these materials were also very efficient (>75%). On the contrary, the application of IEs allowed for obtaining the best results of both, sorption and desorption processes when using D2EHPA (75% and 72%, respectively). The application of PMs and IEs is part of the green chemistry, and the conducted elimination of chromium(VI) ions using developed materials allows for the conclusion that they can potentially be used on a larger scale, e.g., for the treatment of industrial wastewater rich in Cr(VI) ions.
