Sequential injection analysis for mercury ion with modified screen – printed carbon electrode

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