A novel modified carbon paste electrode with vinylferrocene/multiwall carbon nanotubes
was fabricated. The electrochemical response of the modified electrode toward morphine
was studied by means of cyclic voltammetry (CV), chronoamperometry (CA) and
electrochemical impedance spectroscopy (EIS). The structural morphology of the modified
electrode was characterized by SEM technique. The prepared electrode showed an
excellent electrocatalytic activity in the oxidation of morphine, leading to remarkable ...
