摘要：

N-(3,4-dihydroxyphenethyl)-3,5-dinitrobenzamide modified multiwall carbon nanotubes paste electrode was used as a voltammetric sensor for oxidation of penicillamine (PA), uric acid (UA) and tryptophan (TP). In a mixture of PA, UA and TP, those voltammograms were well separated from each other with potential differences of 300, 610, and 310 mV, respectively. The peak currents were linearly dependent on PA, UA and TP concentrations in the range of 0.05-300, 5-420, and 1.0-400 mu mol L(-1), with detection limits of 0.021, 2.0, and 0.82 mu mol L(-1), respectively. The modified electrode was used for the determination of those compounds in real samples.
