“…[32] D2EHPA exhibits the ability to engage in dipole-dipole interactions and possesses a high hydrogen-bonding capacity except for its lipophilicity, and it possesses good compatibility with PVC. [70] Since the selectivity of acidic carriers is very low, their selectivity can be modulated by pH control. [25] Meanwhile, studies have illustrated that the type of acidic carrier can affect the transport stability of the PIM.…”

“…Rapid development of the new energy vehicle industry has brought pressure on the demand and supply of lithium resources; thus, massive efforts have been made by PIMs to recover and extract lithium from salt lake brines, which are the largest lithium resource reserves around the world.

Polymer inclusion membranes (PIMs) have gained significant attention in the field of metal separation and recovery due to their high selectivity, long service life, high stability, flexible design and low cost. Over the past 10 years, interest around PIMs has increased considerably; hence, the number of research papers has grown exponentially. This review provides the preparation methods and composition of PIMs, presents an overview of studies on PIMs reported since 2012, and discusses the relationship between the physicochemical properties of different types of membrane components and the microstructure, selectivity, transport performance and stability of prepared PIMs. This review also elucidates the metal transport mechanism at the interface and interior of PIMs and summarizes the modification and separation intensification methods of PIMs. Additionally, the structure and stability of PIM relative to other liquid membranes are also discussed. Finally, the existing challenges and perspectives of PIMs in the field of metal separation and recovery are proposed and highlighted. Notably, the need for highly selective and low‐cost carriers, a deeper understanding of membrane microstructure and separation mechanisms, and strategies for promoting widespread adoption of polymer inclusion membrane‐electrodialysis technology deserve particular consideration, which are of guiding significance for accelerating the industrialization process of PIMs.

“…However, due to the low stability of CTA-based PIM, it was used only in four consecutive extraction/back-extraction experiments 38 . Kazemi et al 39 , 40 showed the extraction-recovery of bismuth(III) as cationic form from its sulfate solution by using PVC-based PIM comprised of 50/50 wt% PVC/D2EHPA. It was shown that PVC-based PIM had suitable stability.…”

This study is the first application of a PVDF-HFP-based polymer inclusion membrane incorporating the poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP) and di(2-ethylhexyl)phosphoric acid (D2EHPA) as the base polymer and extractant for the extraction of bismuth(III), respectively. It is demonstrated that the PIM comprised of 60 wt% PVDF-HFP and 40 wt% D2EHPA is the most effective in the extraction of bismuth(III) from feed solution containing 20 mg L−1 bismuth(III) and 0.2 mol L−1 sulfate adjusted to pH 1.4. The extracted bismuth(III) ions are back-extracted quantitatively to the receiving solution containing 1 mol L−1 sulfuric acid. The stoichiometry experiments reveal that the Bi: D2EHPA ratio in the bismuth(III) extracted complex is 1:6, and D2EHPA is dimer. Moreover, it is shown that the studied PIM has high selectivity in the extraction of bismuth(III) over other interfering ions such as Mo(VI), Cr(III), Al(III), Fe(III), Ni(II), Zn(II), Cd(II), Co(II), Cu(II), and Mn(II). The interference of Fe(III) is also eliminated by masking with fluoride, leading finally to a nearly pure extraction of bismuth(III).

“…22 We have recently involved with the application of a variety of polymer inclusion membranes for the extraction-recovery of V(V), 5,20,23 Cr(VI) 18 and Bi(III). [24][25][26] The PIMs composed of poly(vinylidenefluoride-cohexafluoropropylene)/trihexyltetradecylphosphonium chloride/2-nitrophenyloctyl ether (PVDF-HFP/ Cyphos ® IL101/NPOE), 20 and poly(vinylidenefluorideco-hexafluoropropylene)/tricaprylmethylammonium chloride/dibutyl phthalate (PVDF-HFP/Aliquat ® 336/DBP) 23 exhibited interesting results for the extraction-separation of V(V). However, using a cost-effective base polymer than PVDF-HFP, on one hand, and a greener plasticizer, on the other hand, convinced us to follow the preparation of a PVCbased PIM containing Aliquat ® 336 as extractant and oleic acid as the green plasticizing agent.…”

Polymer inclusion membranes (PIMs) have received much attention as a greener method than other liquid membranes for the separation of a great number of chemical species. The expected horizon of industrial applications besides the advantages of greener characteristics of PIMs than other liquid membranes and solvent extraction methods, have resulted in development of the new PIMs for specific tasks. In the presented study, a PIM composed of polyvinyl chloride, Aliquat® 336, and oleic acid (50/40/10 wt%, respectively) is fabricated and its characteristics are studied. Membrane segments (3.5 cm diameter, 0.110 ± 0.013 g) can extract 73% of V(V) (initial concentration 50 mg L−1) from 50 ml Na2SO4 solution (0.1 M) adjusted to pH 2.5 after 8 h shaking. The extraction is proceeded by an anion exchange mechanism in which chloride anion of the extractant is replaced by VO2SO4−. It is approved that ~97% of the extracted amount of V(V) is back‐extracted from the loaded PIMs by contacting them, for 24 h, with 50 ml 7 mol L−1 H2SO4/0.25 v/v% of H2O2. The PIM extracts selectively V(V) from the simulated solutions like that obtained by digestion of spent alumina hydrodesulfurization catalysts.
