Abstract
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 its complexation with Bi ion. The limit of detection of the sensor was 0.8 ng/mL.
