“…In Table 6, the variation of the initial As it can be seen, the value of the initial flux for Pd(II) decreased slightly from 3.28 to 3.05 lmolm -2 s -1 . This observation confirms low tendency to leach the ion carrier from membrane matrix like in the earlier studies (Pospiech 2015a, b). Membrane with TOMATS has good stability, because the decrease in the initial flux is very small.…”

This work focuses on the application of polymer inclusion membrane (PIM) with tricaprylmethylammonium thiosalicylate, [A336][TS] (TOMATS), a thiol-containing task-specific ionic liquid for the transport of Pd(II) ions from aqueous solutions. 0.3 M thiourea in 0.1 M hydrochloric acid was found the most effective stripping phase in the transport of Pd(II) from membrane phase containing TOMATS. Separation of Pd(II) ions was also carried out from hydrochloric acid solution containing Pt(IV), Fe(III), Ni(II), and Mn(II). Pd(II) ions were preferably transported in the presence of these metal ions. The separation coefficients followed the order:[TS] proved to be an excellent ion carrier for Pd(II) from hydrochloric acid solution. The results also showed that transport efficiency of the PIM was reproducible and it can be useful for the development of the simple and highly effective method of Pd(II) recovery from leach liquor of spent catalysts.

“…This phosphonium ionic liquid has been not used yet as an ion carrier in PIMs for separation of Cd(II) over Co(II) and Ni(II). In the previous paper, Cyphos IL 104 (trihexyl(tetradecyl)phosphonium bis(2,4,4-trimethylpentyl)phosphinate) was used as the extractant/ion carrier of Cd(II) in the solvent extraction and transport processes through PIM [32]. In this investigation, several factors were studied in order to determine the optimal condition of selective transport of Cd(II) over Co(II) and Ni(II) from hydrochloric acid solutions across PIM.…”

This paper presents study on the facilitated transport of cadmium(II), cobalt(II) and nickel(II) ions from aqueous chloride solutions through polymer inclusion membranes (PIMs) with phosphonium ionic liquid. Cyphos IL 101 (trihexyl(tetradecyl) phosphonium chloride) was used as a selective carrier for synthesis of cellulose triacetate membranes containing o-nitrophenyl pentyl ether (ONPPE) as a plasticizer. Effect of different parameters such as hydrochloric acid concentration in the source phase as well as ion carrier concentration in the polymer membrane on metal ions transport has been investigated. Cd(II) was transported preferably from hydrochloric acid solutions containing Co(II) and Ni(II) through PIM containing 18.8 wt.% CTA and 26.0 wt.% Cyphos 101 and 55.1 wt.% ONPPE into 0.5 M HNO 3 as the receiving phase. The obtained results suggest that there is a possibility of application of this membrane with Cyphos IL 101 as ion carrier for separation of Cd(II) over Co (II) and Ni(II) from hydrochloric acid solutions.Keywords: cadmium(II), cobalt(II), nickel(II), Cyphos IL 101, polymer inclusion membrane Przeprowadzono badania transportu jonów Cd(II), Ni(II) i Co(II) z wodnych roztwo rów kwasu solnego przez polimerowe membrany inkluzyjne (PIMs) zawierające fosfoniową ciecz jonową -Cyphos IL 101 (chlorek triheksylo(tetradecylo) fosfoniowy) w roli selektywnego przenośnika jonowego. Rolę polimerowej matrycy w membranie pełnił trioctan celulozy (CTA). Jako plastyfikatora użyto eteru nitrofenylopentylowego (ONPPE). W wyniku badań określono wpływ różnych czynników, takich jak stężenie kwasu solnego w fazie zasilającej, jak również stężenie przenośnika w polimerowej membranie na selektywność i efektywność transportu badanych jonów metali. Jony kadmu(II) były selektywnie transportowane z roztworów kwasu solnego zawierającego jony niklu(II) i kobaltu(II) do 0,5 M roztworu kwasu azotowego(V). Uzyskane wyniki wskazują, że istnieje możliwość zastosowania procesów transportu przez polimerowe membrany inkluzyjne z cieczą jonową w roli selektywnego przenośnika do rozdzielania jonów Cd(II) od Ni(II) i Co(II) z roztworów kwasu solnego.

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.
