摘要：
Palladium nanoparticles supported on MWCNTs (Pd/MWCNTs) were successfully prepared by a simple ethylene glycol reduction method in an oil bath. An electrochemical sensor based on Pd/MWCNTs nanocomposite-modified glassy carbon electrode was fabricated for the determination of methyl parathion by differential pulse voltammetry measurement. A highly linear response to methyl parathion in the concentration ranging from 0.10 mu g mL(-1) to 14 mu g mL(-1) was observed, and a detection limit of 0.05 mu g mL(-1) was obtained with the calculation based on signal/noise=3. The present work provides a simple and rapid approach to the detection of methyl parathion.
