Study of ionic liquids by the method of voltammetry at the interface between two immiscible electrolytes


Ionic liquids have been studied as organic phase in the method of voltammetry between two immiscible electrolytes. Polarization of the interface between ionic liquid and water was studied; the dependence of the polarization range ("potential window") on the ionic liquid solubility in water was shown. It was established, that interface between H2O and ionic liquid based on hydrophobic substituted phosphonium cation and tris(pentafluoroethil)-trifluorophosphate anion is polarizable in a range of potential about 500 mv, that gives the chance to determine concentration of some anions, in particular perchlorate and nitrate even at joint presence and also to measure solubility in water of the more hydrophilic ionic liquids.
Key words: ionic liquids, polarization of the interface between two immiscible electrolytes, polarization, solubility in water.
