A carbon paste electrode with added multiwall carbon nanotubes chemically modified
with N-(3, 4-dihydroxyphenethyl)-3, 5-dinitrobenzamide was used as the electrochemical
sensor for the determination of trace amounts of isoprenaline. The modified electrode
showed good electrocatalytic activity for the anodic oxidation of isoprenaline, which was due
to a substantial decrease in the anodic overpotential. Under the optimum conditions,
measurements using square wave voltammetry had a linear range in the range of 0.3 to ...
