摘要：

A method for determination of L-dopa by the adsorption stripping voltammetry (ASV) using a multiwalled carbon nanotubes (MWNTs)-Nafion modified glassy carbon electrode (GMGCE) was proposed. This chemically modified electrode (CME) shows a better stability. A sensitive oxidation peak was observed and the anodic peak potential is ca. 0.374V (vs. SCE). The influences of various experimental parameters on the current peak were completely studied. Under the optimized condition, the method has been applied to the determination of L-dopa in samples.
