Description
Summary:In this work, we present a simple, fast, and cheap procedure for the determination of mercury [Hg(II)] by square wave anodic stripping voltammetry (SWASV) at nanocomposite screen-printed graphite electrodes. The nanocomposite surfaces were obtained by the electrodeposition of poly(L-aspartic acid) on graphite screen-printed working electrodes using cyclic voltammetry (CV) and, then, of gold nanoparticles using chronoamperometry. A calibration curve by SWASV was obtained with a wide dynamic range (1–60 μg/L) and a limit of detection of 0.25 μg/L. The developed sensor was applied for the analysis of novel food samples.
