Ionic Liquid-Carbon Nanotube Modified Screen-Printed Electrodes and Their Potential for Adsorptive Stripping Voltammetry

Abstract:

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) (95:5w/w) composite electrode to be useful for adsorptive stripping voltamm...
