The electroreduction of nitrate in synthetic seawater was investigated by cyclic voltammetry (CV) at a bare gold electrode modified by electrodeposited silver nanoparticles (AgNPs). The AgNPs were generated by chronoamperometry using a charge, Q, lower than the theoretical one corresponding to a silver monolayer. In these conditions, a linear range for nitrate determination is obtained from 10·10-6 mol L-1 to 10·10-3 mol L-1. Such a low limit of detection was achieved due to the combination of two chemical reactions coupled with electron transfer. 相似文献
