Determination of heavy metal by voltammetry method

Rapid industrialization and urbanization have caused contamination of the environment by heavy metals, and their rates of mobilization and transport in the environment have greatly accelerated. Environmental pollution of heavy metals is increasingly becoming a problem and has become of great concern due to the adverse effects it is causing around the world. Therefore, it is important to develop simple and rapid methods for the accurate and sensitive determination of heavy metals. In this study, it is aimed to determine heavy metal ions by voltammetric method, which is one of the electrochemical methods, using the synthesized CuFe2O4-rGO composite. The determination of Zn2+ and Cd2+ heavy metals was performed using differential pulse anodic stripping voltammetry (DPASV) technique with CuFe2O4-rGO/GCE. For this purpose, experimental parameters such as electrolyte type, electrolyte concentration, electrolyte pH, deposition potential and deposition time and substrate concentration were examined and optimum conditions of the parameters affecting the response current were determined.
