| 英文摘要 | In this work, silver nanoparticles (AgNPs) were self-assembled on the micro-needle electrode (MNE) with the help of chitosan (CTS) and polyvinylpyrrolidone (PVP) and used for the amperometric (i-t) determination of nitrate (NO3?) in seawater samples. CTS/PVP was electrodeposited on the MNE surface to improve the conductivity and specific surface area of the MNE, and to provide reduction conditions needed for Ag+ reduction and strong binding affinity for combination of AgNPs which had excellent catalytic activity for NO3?. AgNPs were selfassembled uniformly on the surface of MNE with the diameter of about 150?400 nm. Thanks to the unique aciform structure of MNE, the outstanding adhesion ability of CTS/PVP, and the excellent electrocatalytic ability of AgNPs, the so-prepared AgNPs/CTS/PVP/MNE showed significantly improved performance and stability for the amperometric determination of NO3?. Under the optimal conditions, the AgNPs/CTS/PVP/MNE was found to have a wide linear range (5?2000 ?M) and a low limit of detection (1.2 ?M). Furthermore, the AgNPs/CTS/PVP/ MNE was successfully used for the direct determination of NO3? in coastal seawater samples with satisfactory results. |
