Abstract
Solvent extraction of Zr(IV) in ionic liquid (IL) medium is less known and Zr(IV) - IL chemistry indeed needs exploration to realize the coordination approach of Zr(IV) in IL phase. In view of this, in the present work, a strongly hydrophobic imidazolium based IL: 1-methyl-3-octylimidazolium bis(trifluoromethylsulfonyl)imide ([C8mim][NTf2]) as the medium containing a diglycolamide (DGA) extractant: N,N,N',N'-tetra-n-octyldiglycolamide (TODGA) was opted to understand the extraction behavior of Zr(IV) from nitric acid medium. Different experimental parameters such as the concentration of initial nitric acid, initial feed metal concentration, equilibration time and ligand concentration were tuned to unravel the extraction efficiency of the proposed IL phase towards Zr(IV). The extraction scenario was completely dependent on the hydrophobicity of IL diluent and increasing extraction trend with an increase in feed acidity along with the coordination of two TODGA molecules ensured Zr(IV) - complex formation in a neutral solvation mechanistic pathway. The extraction trend of Zr(IV) was compared with molecular diluent (n-dodecane (n-DD)) containing TODGA and a phase modifier: N,N-dihexyloctanamide (DHOA). The coordination aspect of Zr(IV) with ligand in IL phase was ascertained spectroscopically to validate Zr(IV) loading in IL phase. Thermodynamics of Zr(IV) extraction revealed the nature of the extraction process and the complex formation.

Rout A, Ramanathan N. Extraction and Selective Separation of Zr IV from Ln III/An III Using an Undiluted Phosphonium Ionic Liquid. Chempluschem 2024; 89:e202300406.

Abstract
Solvent extraction of Zr(IV) in an undiluted phosphonium based ionic liquid (IL) and its selective separation from Ln(III) and An(III) has been investigated in the present study. Eu(III)/Am(III) were chosen as the representative Ln(III)/An(III). Tri(hexyl)tetradecylphosphonium nitrate ([P66614][NO3]) was chosen as IL phase and the feed phase was nitric acid containing the target metal ions. The extraction process was accomplished at different experimental parameters such as the concentration of initial nitric acid, initial feed metal concentration and equilibration time to explore the extractability of the proposed IL towards Zr(IV). The efficient extraction of Zr(IV) without any external ligand in IL phase and negligible extraction of Eu(III)/Am(III) were distinctly discerned leading to noteworthy separation factors for Zr(IV). The loading experiment revealed a noticeable growth of equilibrium concentrations of Zr(IV) in IL phase while that of Eu(III) was very less irrespective of the initial feed concentration. The association of two IL moieties in the complex formation process has been inferred. Nitrate ion was found to be superior as IL anion in terms of metal loading in comparison to other anions. Thermodynamics of extraction and the stripping of the loaded Zr(IV) from IL phase using a suitable stripping solution have also been investigated.

Abstract
The salt metathesis reaction of Na(pmtz)·H2O [pmtz- = 5-(pyrimidyl)tetrazolate] and PuBr3·nH2O in an aqueous media leads to the formation of the mononuclear compound [Pu(pmtz)3(H2O)3]·(3 + n) H2O (Pu1, n = ∼8) that is isotypic with the lanthanide compounds [Ln(pmtz)3(H2O)3]·(3 + n) H2O (Ln = Ce-Nd). Dissolution and recrystallization of Pu1 in water yields the dinuclear compound {[Pu(pmtz)2(H2O)3]2(μ-pmtz)}2(pmtz)2·14H2O (Pu2), which is isotypic with the lanthanide compounds {[Ln(pmtz)2(H2O)3]2(μ-pmtz)}2(pmtz)2·14H2O (Ln = Nd and Sm). Like their nine-coordinate ionic radii, the M-O and M-N bond lengths in Pu1/Pu2 and Nd1/Nd2, respectively, are within error of one another. The Laporte-forbidden 4f → 4f and 5f → 5f transitions are also assigned in the UV-vis-NIR spectra for these f-element tetrazolate coordination compounds.

Abstract
The contribution of oleyl amine as a biodegradable and simple aliphatic compound containing amine functional group (-NH2) was discussed in this work with respect to the remediation process of heavy metal ions from aqueous solution. Manganese oxide nanoparticles were synthesized via combustion synthesis and then functionalized with oleyl amine to form a new nanosorbent (NMn3O4-OA).The characteristics of this nanosorbent were examined using different instruments, such as Fourier-transform infrared spectroscopy, thermal gravimetric analysis, X-ray powder diffraction and high-resolution transmission electron microscopy. The HR-TEM images confirmed nanoscale range for NMn3O4-OA between 41.30 and 61.86 nm. The influence of diverse parameters on remediation of ZnII/CoII was examined, involving pH of metal ion solutions (pH 1-7), reaction time (1-60 min), solid amount (5-100 mg) and ionic concentration (0.1-2.0 mol/L). The optimum conditions were found pH 7 and 5-20 min reaction time for the two metal ions. The maximum capacities for adsorptive remediation were found 202 and 100 mgg-1for ZnII and Co II, respectively.

Abstract
New magnetic silica imidazolium ionic liquid nanocomposites were synthesized by a sol-gel technique. The (3-aminopropyl)triethoxysilane (APTS) was condensed with glyoxal and p-hydroxybenzaldehyde in acetic acid to produce an amino-modified silica ionic liquid (Si-IIL). The APTS was condensed with TEOS in ethanol and water to prepare amino-modified SiO2 nanoparticles. The produced amino-modified SiO2 silica was condensed with glyoxal and p-hydroxybenzaldehyde in acetic acid to produce chemically bonded silica SiO2-IIL. The SiO2-IIL and Si-IIL were used as capping agents during and after the formation of magnetite nanoparticles in ammonia to produce magnetic SiO2-IIL-Fe3O4 and Fe3O4-Si-IIL adsorbents, respectively. Their chemical structure, morphology, crystalline lattice structure, surface charges, particle sizes, and magnetic characteristics elucidated the formation of core-shell and highly dispersed magnetic nanocomposites. The saturation magnetization values of Fe3O4-Si-IIL and SiO2-IIL-Fe3O4 were 35.3 and 30.8, respectively. The uniform dispersed disconnected spherical morphologies appeared for Fe3O4-Si-IIL hybrid and the core-shell spherical morphology obtained with SiO2-IIL-Fe3O4 hybrid NPs. The Fe3O4-Si-IIL and SiO2-IIL-Fe3O4 show an excellent high chemical adsorption capacities as 460.3 and 300.9 mg·g-1, respectively (not reported in the literature) when used as an adsorbent to remove CB-R250 water pollutant under optimum conditions. Their applicability and reusability as fast and highly effective adsorbents for Coomassie blue (CB-R250) organic water pollutants were investigated.

Abstract
In contrast to molecular diluents, diglycolamide (T2EHDGA) and carbamoylmethyl-phosphine oxide (CMPO) extractants diluted in an ionic liquid diluent minimize aggregation upon nitric acid extraction and prevent third phase formation during the course of solvent extraction.
