“…They show extraordinary properties such as an extremely low vapor pressure, high thermal stability, and high viscosity, and their physicochemical properties can be tuned by modifying their chemical structure (being Btaskspecific^ionic liquids) (Stojanovic et al 2010). Among other uses, IL have successfully been applied as extractants for metals and metal-containing compounds in wastewaters (Stojanovic and Keppler 2012;Fisher et al 2011).…”

A polymer inclusion membrane (PIM) made of cellulose triacetate as a polymer and the task specific ionic liquid (IL) trioctylmethylammonium thiosalicylate (TOMATS) was assembled as a new Diffusive Gradients in Thin film (DGT) device to test its efficiency as a binding phase for mercury (Hg) monitoring. The effect of IL content was assessed, showing that higher TOMATS percentage is better for short deployment studies (up to hours), whereas for long-term exposure (up to days), a lower content can be more suitable. Different configurations of PIM-DGT samplers have been tested under controlled conditions and compared with in-house DGT conventional ones, manufactured with thiol groups as resin layer, for the determination of labile Hg. According to our results, a nonlinear accumulation profile of Hg with deployment time for the different designs of PIM-DGT was observed, limiting the range of applicability of the DGT technique. Promising results for the efficient removal of Hg from aqueous solutions and/or environmental monitoring studies were obtained with TOMATS.

“…[34] They also proved that TOMATS can extract heavy metals by forming metal-thiolate and additionally a complex-bond with the carboxylate group of the thiosalicylate anion, favoring the extraction process.…”

“…The physicochemical properties of the ion carrier (e.g., density, viscosity), the cation and anion combination, as well as the presence of the sulfur in the functional group of ionic liquid are essential factors strongly influencing the extraction efficiency and transfer of metal ions from the aqueous solutions (Fisher et al 2011). Therefore, the study of the transport of Pd(II) through PIM with TOMATS can provide important knowledge concerning the efficiency and selectivity of the separation process applying this IL as the ion carrier.…”

“…TSILs contain functional groups appended to the cation and can extract metal ions without the ion exchange. The literature review shows that this TSIL is the excellent extractant of heavy metal ions, such as Hg(II), Cu(II), Ag(I), Fe(III), Cd(II), and Pb(II) from aqueous solutions (Kogelnig et al 2008;Egorov et al 2010;Fisher et al 2011). Spent catalysts and electronic scraps are potential source of palladium (Cieszynska and Wisniewski 2012;Saternus and Fornalczyk 2013;Lee et al 2010).…”

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.
