Rapid Preparation of Room Temperature Ionic Liquids with Low Water Content as Characterized with a ta-C:N Electrode

Popis výsledku v původním jazyce

Room temperature ionic liquids (RTILs) provide an ionic, solvent-free medium for electrochemical reactions. RTILs are appreciated for their many unique properties; nevertheless, it is precisely these qualities that can be very easily debased by water andorganic impurities. Water, as a major contaminant in hygroscopic RTILs, has a strong effect on the physical and electrochemical properties (e.g., viscosity and dielectric constant, hence the background voltammetric current, diffusion coefficient of redox analytes and electron-transfer kinetics). In this work, a simple and relatively rapid purification process was investigated that involves sparging ultrahigh purity Ar through the RTIL while being heated at 70 degrees C (so-called sweeping). A more conventional vacuum drying method at 80 degrees C was used for comparison. The electrochemical properties of two RTILs, [BMIM][BF4] and [EMIM][BF4], were assessed voltammetrically using a nitrogen-incorporated tetrahedral amorphous carbon (ta
