Electrodes with enhanced active surface area were successfully synthesized by electrochemical methods using excellent L-glutathione nanostructured materials, prepared with the aim of eliminating heavy metals that may endanger human health, particularly in beverages. Most importantly, through these electrochemical methods, high-performance L-glutathione nanostructured electrodes can be directly fabricated at room temperature and atmospheric pressure, in a cost-effective manner, without the need for additional steps or extensive processing. Furthermore, with this method, L-glutathione nanostructures of desired composition, structure, and size could be easily synthesized by controlling electrochemical parameters such as potential and time. The nanostructured layers of the electrodes not only provide higher and more stable structural properties but also demonstrate significant morphological effects on electrode performance. Since this thin film formation is carried out electrochemically directly on ITO, interfacial defects and other contact-related problems are minimized. The surface morphology of the prepared three-dimensional (3D) electrodes was characterized using scanning electron microscopy (SEM). The functional groups and optical properties of L-glutathione thin nanostructured films were analyzed by Fourier transform infrared spectroscopy (FTIR) and UV-VIS spectroscopy. In addition, in the application stage, inductively coupled plasma mass spectrometry (ICP-MS) was employed to determine the heavy metal removal capacities of these electrodes.
