“…Studies were carried out to compare the use of CTA and PVC as base polymer of PIM with Aliquat 336 [28] and Cyphos IL 101 and 104 [29]. Under the optimum condition, in Cr (VI) permeation with PIM including Aliquat 336, the permeation rates of CTA-and PVC-based membranes were comparative, while in Zn (II) permeation with PIM including Cyphos IL 101 or 104, transport abilities of CTA-based membranes were much beter than those of PVC.…”

Metals are widely used in various areas of human life, and their existence in the environment at high concentrations has become a cause for concern. Metals can enter the human body and disturb the human metabolic system. Therefore, research to recover metals from their matrix both from industrial wastewater and from ores or scraps containing metals is of great importance. One of the separation techniques proposed to overcome those issues involves using supported ionic liquid membranes (SILMs). This chapter summarizes the recovery of metals using SILM. In SILM, an ionic liquid that acts as an extractant is embedded in small pores of a polymer support. The latest type of physical impregnation of ionic liquid, which is the type most commonly used in metal separation, is called polymer inclusion membrane (PIM). PIMs were prepared by casting a solution containing an ionic liquid, a plasticizer and a base polymer to form a thin, lexible and stable ilm. A PIM including ionic liquids has a similar coniguration to SILM, and it is considered to be a kind of SILM. In this chapter, efects on the stability and selectivity in SILM and PIM for metal separation are reviewed.

“…Some authors proposed ionic liquids (ILs), e.g. methyltrioctylammonium or trihexyl(tetradecyl)phosphonium salts, as metal ion carriers in PIMs . The interest in application of ILs for separation processes has been increasing recently because ILs exhibit many unique properties such as high thermal stability, non‐flammability and extractability for different organic and inorganic compounds.…”

“…Until now PIMs containing various ion carriers have been proposed for separation of a variety of metal ions, i.e. noble metals, actinides, lanthanides, and heavy metals, such as zinc, iron, cadmium, copper, nickel, lead, chromium, mercury, cobalt, and manganese . Also, PIMs were applied for the transport of such organic compounds as oxalic, tartaric, lactic or citric acid …”

“…Our team described the removal of Zn(II), Fe(II) and Fe(III) from single‐metal‐ion chloride aqueous solutions with PIMs containing trihexyl(tetradecyl)phosphonium chloride (Cyphos IL 101) or trihexyl(tetradecyl)phosphonium bis (2,4,4‐trimethylpentyl)phosphinate (Cyphos IL 104) as metal ion carriers and showed that Cyphos IL 101 is a more effective carrier of Fe(III) than of Zn(II).

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

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.
