摘要:
A novel method has been developed for the determination of p-nitrophenol (p-NP), which was based on the enhanced electrochemical response of p-NP at an acetylene black paste electrode coated with salicylaldehyde-modified chitosan (denoted as S-CHIT/ABPE). In 0.2 mol L−1 HCl solution, p-NP yielded a sensitive reduction peak at −0.348 V. Compared with the poor response at conventional carbon paste electrode, S-CHIT/ABPE remarkably increased the peak current of p-NP. All the experimental conditions, which influence the electrochemical response o...
