Voltammetric determination of bismuth was made using a carbon paste electrode modified with carbon nanotube-encapsulated rubeanic acid. The anodic stripping voltammetry on the MWCNTs@Rubeanic acid composite electrode exhibited well-defined, sharp and undistorted peaks with a favorable resolution for bismuth. Comparing a non-encapsulated MWCNTs composite electrode with an in-situ capsulated MWCNTs@Rubeanic electrode, the MWCNTs@Rubeanic composite electrode exhibited superior performance due to…

Transduction mechanism of carbon nanotubes in solid-contact ion-selective electrodes.
The ion-to-electron transduction mechanism of carbon nanotubes is studied by using electrochemical impedance spectroscopy (EIS) and cyclic voltammetry (CV) and the impedance response of GC/SWCNT is very similar to that of poly(3,4-ethylenedioxythiophene) (PEDOT) film electrodes studied earlier.
