“…In this context, ammonium and phosphonium based ILs with long alkyl chains are regarded as the best suited solvent in place of imidazolium ILs. Their low density as compared to the aqueous phase, extreme hydrophobicity, cost‐effectiveness and simple coordination pathway offer good sustainability to the process [17–43] . Among this category of ILs, the use of phosphonium based ILs, especially Cyphos 101(trihexyl(tetradecyl)phosphonium chloride ([P 66614 ][Cl])) and its derivatives show an abrupt growth in the current literature dealing with the metal separation by ILs [31–40] .…”

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.
