“…Regel-Rosocka et al [26] prepared the PIM using CTA as a support and Cyphos IL 101 as carriers to remove Zn(II) and Fe(III) from chloride solution. Although the highest Zn(II) lux was obtained for membrane without plasticizer, with the highest Cyphos IL 101 content, the membranes with o-nitrophenyl octyl ether as a plasticizer have been selected because of their beter mechanical properties.…”

“…Cyphos IL 101 diluted in organic solvent is extensively studied to extract metal ions such as Zn(II), Fe(III), Pd(II) and U(VI) [26,[45][46][47][48]. Cyphos IL 104 and 109 ((trihexyl)tetradecylphosphonium bis(triluoromethylsulphonyl) imide) are also used as the extractants for Zn(II), Fe(III), Cd(II), Cr(VI) and lantanides [26,[49][50][51] and Au(III) [52].…”

“…A number of reports on SLM described the use of diluted ionic liquids. Fe(III) and Zn(II) were transported through a PIM composed of Cyphos IL 101 and CTA or PVC [26,58]. Sulphuric acid was found to be an efective stripping phase.…”

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.

“…form anionic species in hydrochloric acid solution of high concentration. Therefore, from concentrated HCl, these metals are extracted by Cyphos IL 104 according to anion exchange mechanism (Cieszynska and Wisniewski, 2012;Regel-Rosocka et al, 2012;Rybka and Regel-Rosocka, 2012). With the aim of simulating the processing of the acidic leach liquors generated during the leaching of rare earths containing ores and secondary resources (N-Metal hydride batteries, spent fluid cracking catalysts, etc.…”
