Abstract
AbstractCyclic voltammetry is used to study the transfer of a series of cations and anions across a room‐temperature ionic liquid membrane composed of tridodecylmethylammonium cation and tetrakis[3,5‐bis(trifluoromethyl) phenyl]borate anion. It is shown that the addition of water‐soluble crown ether (e.g. 18‐crown‐6) to the aqueous phase makes it possible to distinguish the voltammetric responses of alkali and alkaline earth metal cations. The determination of low concentrations of K+ (0.05–0.3 mM) in the presence of an excess of Mg2+ (1 mM) in water is demonstrated as a model application of an amperometric ion‐selective electrode for K+.
