Potentiometric
multisensor system of anion-selective electrodes based on ionic liquids
Abstract
The possibility
to use solid-state and liquid PVC-membrane electrodes based on ionic liquids
for creation of potentiometric multisensor system was assessed. Ionic liquids
with 1,3-dihexadecylimidazolium cation and chloride, bromide, iodide and
nitrate anions were used. Cross-sensitivity parameters of the sensors have been
determined. Multisensor array has been applied to the determination the
chloride and iodide anions in a multicomponent mixture. Discrimination of
mineral waters of various compositions using the developed system was carried
out by applying the method of principal component analysis.
Key words: Ionic
liquids, solid-state ion-selective electrodes, multisensor system.
