Sažetak
Ion transfer reactions across a liquid interface between an aqueous electrolyte and 1-hexyl-3- methylimidazolium tris(pentafluoroethyl)trifluorophosphate ([hmim] [fap]) room temperature ionic liquid (RTIL) were studied with the help of three-phase electrodes. The electrode assembly comprised edge plane pyrolytic graphite modified with a thin layer of [hmim][fap] containing lutetium bis(tetra-tert- butylphthalocyaninato) (Lu[tBu4Pc]2) as a redox probe. Lu[tBu4Pc]2 can be oxidized and reduced to a stable hydrophobic monovalen cation and anion, respectively, hence allowing interrogation of the transfer of cations and anions in one and the same voltammetric experiments. In spite of the strong hydrophobicity of the salt [hmim][fap], the electrode reactions of the redox probe studied in contact with various inorganic aqueous electrolytes, were frequently accompanied by expulsion of ions constituting the RTIL into the aqueous phase. Using ionic chromatography it was found that the distribution of ions in the aqueous electrolyte/RTIL biphasic system is strongly determined by ion exchange reactions. The affinity of the ions of the RTIL for the aqueous phase was assessed with respect to the water/nitrobenzene (w/nb) system, and the following Gibbs energies of the transfer were found: = -16.6  0.9 kJ mol-1 and = -22.4  0.3 kJ mol-1.
