Polymer inclusion membranes (PIMs) have been prepared using cellulose triacetate (CTA) as polymer and derivatives of the commercial ionic liquid (IL) Aliquat 336, trioctyl methylammonium chloride (AlqCl), as extractants. The different ILs were prepared by exchanging chloride anion from AlqCl for other more lipophilic anions, obtaining IL derivatives AlqNO3 and AlqSCN. PIMs containing these extractants...
Physical–chemical characterization of supported liquid membranes (SLMs), that is, a porous structure containing room temperature ionic liquids (RTILs) was carried out by analyzing XPS and FTIR spectra, while determination of cation transport number from concentration potentials measured with the membranes in contact with NaCl solutions gives transport/electrical information. SLMs filled with two different...
