Abstract: (636 Views)
Electrochemical sensors are used as an effective solution for detecting lead in environmental waters, even at micromolar concentrations. In this study, manganese oxide nanostructures were synthesized using sodium dodecyl sulfate surfactant through an electrochemical deposition method, and their electrocatalytic activity was investigated as a low-cost and efficient electrode for detecting lead ions. Scanning electron microscopy was used to analyze the morphology of the nanostructures, while X-ray diffraction (XRD) was employed to identify the crystalline structure, and Fourier-transform infrared spectroscopy (FTIR) was used to confirm the successful synthesis of the nanoparticles. The results indicate that the surfactant influences the morphology of manganese oxide, and the Mno2/SDS nanostructure significantly improved the current response in lead ion detection. The sensing process was carried out using differential pulse voltammetry and cyclic voltammetry techniques, demonstrating that the use of surfactant enhances morphology and increases sensing current.
