CHEM042 - Development of Electrodes for Desalination of Seawater to Utilize Water by a Portable Box

This scientific study investigates the suitability of the Electrodialysis process (ED) for seawater desalination. By 2050, freshwater scarcity may impact two-thirds of the world's population, particularly in island areas surrounded by seawater. Seawater constitutes 96% of global water sources and cannot be utilized directly. The utilization of ED in combination with specific electrodes can lead to a reduction in electrode efficiency. The study undertakes a comprehensive evaluation of the ED process, with a specific focus on determining the optimal voltage, surface morphology, and the most effective electrode pairing. The graph depicting the relationship between potential and time duration provides evidence of stability in voltage application. The experiment conducted within the 4.5-6V range exhibits enhanced voltage stability compared to other ranges. Additionally, SEM images provide evidence of dramatic surface restructuring. These findings support the potential utilization of the 4.5-6V range, as the conductivity remained constant starting from a concentration of 4 mM. This combination offers advantages in terms of ED
