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 ..
