Abstract An ionic liquid-modified carbon nanotubes paste electrode (IL/CNTPE) has been
fabricated using hydrophilic ionic liquid (n-hexyl-3-methylimidazolium hexafluoro
phosphate) as a binder. This electrode showed enhanced electrochemical response and
strong analytical activity towards the direct electrochemical oxidation of diclofenac (DCF).
The electron transfer coefficient, α, and charge transfer resistance (R ct) of DCF at the
modified electrode were calculated. Under optimal conditions at pH 7.0, the anodic peak ...
