• Description:
  Electroanalytical methods or electrochemical sensors involve a group of quantitative and qualitative methods in which an electric excitation function is applied to an electrochemical cell and a response function is measured. Based on the properties of the applied excitation function, they are categorized as potentiometry, voltammetry, impedance spectroscopy, etc. All these methods require the use of electrodes where the electron-transfer reactions occur and an electrolyte, an ionically conducting medium, to transport charge within the electrochemical cells, to establish the electrochemical contact of all electrodes effectively, and to solubilize the reactants and products for efficient mass transport. Ionic liquids (ILs) are a class of compounds containing organic cations or anions that melt at or near room temperature. They represent a new type of nonaqueous and biphasic electrolytes that combine the benefits of both solid and liquid systems. They are shown to have negligible vapor pressure, high ionic conductivity, wide potential window (up to 5.5 V), high heat capacity, and good chemical and electrochemical stability and have been demonstrated as media in electrochemical devices including super-capacitors, fuel cells, lithium batteries, photovoltaic cells, electrochemical and mechanical actuators, and in electroplating. The liquid crystalline structure as well as the solvation properties of ILs has their own significance in many of these applications. In the past, ILs are regarded as completely nonvolatile, but the work of Earle et al. has shown that some ILs may be evaporated and recondensed. However, generally speaking, most ILs have zero vapor pressure at room temperature; thus, there is no drying out of the electrolytes presenting many potential benefits for analytical methods and technique developments in comparison to traditional aqueous and nonaqueous electrolytes/solvents.
