Ionic liquid-carbon nanotube modified screen-printed electrodes and their potential for adsorptive stripping voltammetry
Compared with paraffin oil, the use of ionic liquids as a binder in carbon paste type electrodes was shown to greatly enhance the accumulation of analytes, as illustrated with 17α-ethynylestradiol as a model. The ionic "liquid" n-octyl-pyridinium hexafluorophosphate [C8py][PF6] was most ef...

| description | Compared with paraffin oil, the use of ionic liquids as a binder in carbon paste type electrodes was shown to greatly enhance the accumulation of analytes, as illustrated with 17α-ethynylestradiol as a model. The ionic "liquid" n-octyl-pyridinium hexafluorophosphate [C8py][PF6] was most efficient among several ionic liquids investigated. Such preconcentration allowed a [C8py][PF6]-multiwalled carbon nanotubes (MWCNTs) (95 :5 w/w) composite electrode to be useful for adsorptive stripping voltammetry. Screen-printed electrodes modified with [C8py][PF6]-MWCNTs were developed and were able to achieve high sensitivity during adsorptive stripping voltammetric measurements under optimised conditions. |
