Abstract

In this study, we developed a simple high-throughput and cost-effective method for monitoring toxic metal ion in an environmental aqueous sample. Mercury ion determination with Sequential Injection Analysis system (SIAs) coupled with the electrochemical detection on the modified screen-printed carbon working electrode (SPCE) is an alternative green analysis of mercury ion. The gold film was used as the modified material for improved mercury ion analysis in the automated system without memory effect on the electrode. Mercury oxidation signal was found at the potential of 0.7 V in 0.1 M HNO3 and 1.0 M HCl with the concentration low to 0.25 ± 0.18 mg×L-1. Online sample preparation and separation will study in the further experiment.

改进网印碳电极的汞离子序进样分析

在这项研究中，我们开发了一种简单、高通量、低成本的方法来监测环境水样中的有毒金属离子。顺序进样分析系统(SIAs)与改性丝网印刷碳工作电极(SPCE)电化学检测相结合的汞离子测定是一种替代的绿色汞离子分析方法。采用金膜作为修饰材料，改进了自动化系统中汞离子的分析，对电极无记忆效应。在0.1 M HNO3和1.0 M HCl溶液中，当电位为0.7 V时，在0.25±0.18 mg×L-1范围内发现了汞氧化信号。在线样品制备和分离将在进一步的实验中进行研究。
