“…Thus, the authors postulated that oxidation of solvent also occurs, probably by an Al + -mediation mechanism. According to this mechanism, upon polarization of Al at high potentials, highly reductive intermediates of Al + were generated, , and they migrated to the vicinity of the passivation layer/electrolyte interface, where they subsequently reacted with adsorbed anions or solvents. Thus, the reaction kinetics depend on how readily the anions or solvents are adsorbed on the Al surface or surface layer.…”

“…The high scan rate was identical to that used in an earlier study of the influence of the concentration of water in PC on the polarization behavior of platinum. 12 Unless stated otherwise, the scan rate during polarization was 5 mV/s. CyP curves were generated with a Gamry potentiostat ͑model no.…”

“…Considering the many potential applications of ionic liquids (1,2), it is necessary to formulate methods for determination of common impurities such as water in these systems. Water has been determined in propylene carbonate by voltammetric scans at platinum (3), taking advantage of redox features generated upon repetitive potential cycling. Another physical property of water is its rather strong infrared absorption due to OH stretching vibrations (4).…”

Determination of water in 1-ethyl-3-methylimidazolium tetrafluoroborate has been carried out using both electrochemical and infrared spectroscopic methods. At platinum electrodes, voltammetric responses for water oxidation and reduction have been used to prepare calibration curves. It has been found that the water oxidation current at +2.4V vs Ag/AgCl is suitable for water determination to at least 40 mM. Infrared spectroscopy of water in quartz cells in the OH stretching region revealed an IR feature at 3550 cm -1 for water additions to 20 mM, with another feature at 3650 cm -1 appearing at higher water concentrations. For the lowfrequency feature, a calibration curve is linear to 14 mM. Both electrochemical and IR methods provide a lower limit of detection of approximately 1 mM water in this ionic liquid.
