. 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 × 10−9–1.0 × 10−6 mol · L−1 with a detection limit of 5.0 × 10−10 mol · L−1 in pH = 1.2 solution...
The electrochemical behavior of nuciferine has been studied for the first time. Nuciferine is irreversibly oxidized at high potentials, resulting in the formation of orthoquinone. The amount of the obtained orthoquinone is pH-dependent, and it demonstrates quasi-reversible electrochemical behavior at less positive potential. The concentration of nuciferine was successfully determined by using the...
