“…As can be seen in Table 2, there was only slight variation for the different PIM compositions even though different polymers were employed. These results are in concordance with other publications where similar results were obtained with PIMs prepared with the two polymers, CTA and PVC [13,14].…”

A polymer inclusion membrane (PIM) containing the ionic liquid methyltrioctylammonium chloride (Aliquat 336) as the carrier has been used satisfactorily for the preconcentration of arsenate present in groundwater samples, allowing its determination by a simple colorimetric method. The optimization of different chemical and physical parameters affecting the membrane performance allowed its applicability to be broadened. The transport of As(V) was not affected by the polymer used to make the PIM (cellulose triacetate (CTA) or poly(vinyl chloride) (PVC)) nor the thickness of the membrane. Moreover, the use of a 2 M NaCl solution as a stripping phase was found to allow the effective transport of arsenate despite the presence of other major anions in groundwater. Using the PIM for the analysis of different groundwaters spiked at 100 µg L −1 resulted in recoveries from 79% to 124% after only 5 h of contact time. Finally, the validated PIM-based method was successfully applied to the analysis of waters containing naturally occurring arsenate.

“…These mechanisms are often based on the formation of complexes and ion-pairs with the extractant without the need for large amounts of toxic organic solvents. 15 Solid-phase extraction using PIMs has been proposed for separating various metal ions, such as chromium(VI), 16,17 copper(II), [18][19][20] cadmium(II), [18][19][20] palladium(II) 21 and gold(III). [22][23][24] A PVC-based PIM with Aliquat 336 as the carrier has been found to effectively extract cobalt(II) from 7 mol L -1 hydrochloric acid solutions 25 by the same mechanism as in liquid-liquid extraction.…”

“…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. The CTA-based PIM lost 42% of eiciency after 6 days [28].…”

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.
