摘要
A method for the determination of trace clenbuterol is described. Multi-walled carbon nanotubes (MWCNTs)-Nafion composite was used to modify the glassy carbon electrode (GCE). The modified electrode showed high sensitivity and good selectivity for clenbuterol detection. It offered a linear range of 1.0 x 10(-9)-1.0 x 10(-6) mol . L-1 with a detection limit of 5.0 x 10(-10) mol . L-1 in pH = 1.2 solution. The oxidation mechanism of clenbuterol on the electrode was also investigated.
