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.

“…PIMs are novel type of membranes where the membrane liquid phase (i.e., carrier and plasticizer) is immobilized between the base polymer entangled chains via strong secondary bonds, such as van der Waals force and hydrogen bonds 3,4 . Compared with the supported liquid membranes (SLMs) held by weak capillary force or surface tension, PIMs perform prominent stability in long‐time use and are considered as a green and sustainable alternative to SLMs 5 . Besides the most crucial advantage of high stability, PIMs provide many other advantages such as simple preparation method, high selectivity, versatility, and flexible design 6 .…”

Crosslinking improved ion transport in polymer inclusion membrane‐electrodialysis process and the underlying mechanism

Electric field intensification has been demonstrated as an effective strategy for facilitating ion transfer and separation in polymer inclusion membrane (PIM) involved processes. However, it is still a challenge to develop compatible PIMs with high performance and to reveal the underlying mechanisms. Herein, crosslinked PIMs with different base polymers have been employed in PIM‐electrodialysis processes. Cross‐linked cellulose triacetate (CTA) based PIMs exhibited significant improvement in Cr(VI) transport, which permeability coefficient was 5.9 times larger than the non‐cross‐linked counterpart. The characterizations of cross‐linked PIMs showed higher hydrophilicity and lower membrane area resistance. Furthermore, cross‐linked polymeric network inside CTA based PIMs structure increased their crystallinity, thus supporting the fixed‐site jumping mechanism, thereby enabling ions to be transported directly in a manner of continuous pathway at low current density. This study shed light on further improvement of efficient ion transport and gave insights into the mechanism understanding in PIM‐ED systems.

“…Until now PIMs containing various ion carriers have been proposed for separation of a variety of metal ions, i.e. noble metals, 4,13,14 actinides, [15][16][17] lanthanides, 17 and heavy metals, such as zinc, iron, cadmium, copper, nickel, lead, chromium, mercury, cobalt, and manganese. [1][2][3][6][7][8][9][10][11][12][18][19][20][21][22][23] Also, PIMs were applied for the transport of such organic compounds as oxalic, tartaric, lactic or citric acid.…”

BACKGROUND Hydrometallurgical separation of Zn(II) from Fe(III) from HCl solutions is an important issue to regenerate spent effluents. Polymer inclusion membranes (PIMs) are an attractive technique for selective separation and concentration of low concentrated target metal ions, as an alternative to liquid–liquid extraction. RESULTS PIMs containing phosphonium ionic liquids trihexyl(tetradecyl)phosphonium chloride (Cyphos IL101) or bis(2,4,4‐trimethylpentyl)phosphinate (Cyphos IL104), as metal ion carriers, o‐nitrophenyloctyl ether (NPOE) as a plasticizer and triacetate cellulose (CTA) as a polymer matrix were prepared and characterized by contact angle measurements, scanning electron microscopy, atomic force microscopy and nanoindentation measurements. An important aspect was to determine the influence of PIMs ageing on their morphology and efficiency of Zn(II) transport. Finally, PIMs were applied for separation of Zn(II) from Fe(III). CONCLUSION The surface of the IL‐containing PIMs was characterized as hydrophilic, rough, without apparent pores. However, phase contrast images indicated that the plasticized membranes were not fully homogeneous. Stability of the PIMs, particularly of those without the plasticizer or without the carrier, is affected by ageing. Finally, a membrane‐based successful separation of Zn(II) from Fe(III) was developed with 1 mol L‐1 HCl as a stripping phase for Fe(III), while the majority of Zn(II) were retained in the feed phase (SFe(III)/Zn(II) = 8.85). © 2017 Society of Chemical Industry
