摘要

汞是水生生态系统中最著名的自然和人为有毒污染物之一，可在动植物体内进行生物累积。在这项工作中，我们提出了一种在纳米复合石墨丝网印刷电极上采用方波阳极剥离伏安法检测 Hg(II) 离子的智能检测系统，作为一种可应用于食品质量控制的分析工具。纳米复合表面是通过用聚（l-天冬氨酸）和金纳米粒子对丝网印刷石墨电极进行改性而获得的，并通过电化学技术对其进行了表征。研究人员详尽地研究了电化学和化学合成过程中的实验条件。

Mercury detection in novel foods by a smart pocket sensor

Mercury is one of the most well‐known toxic contaminants of natural and anthropogenic origin in aquatic ecosystems that can bioaccumulate in vegetal and animal organisms. In this work, we propose a smart detection system for Hg(II) ions by square wave anodic stripping voltammetry at nanocomposite graphite screen‐printed electrodes, as an analytical tool to be applied in food quality control. The nanocomposite surfaces were obtained by the modification of screen‐printed graphite electrodes with poly(l‐aspartic acid) and gold nanoparticles and were characterized by means of electrochemical techniques. An exhaustive study of the experimental conditions involved both in the e
