چکیده :

Capacitive deionization (CDI) is a promising water desalination technology, known for its low energy consumption. CDI systems critically depend on the properties of electrode materials. Carbonaceous materials have shown significant potential due to their inherent properties and enhanced ion adsorption. This study explores the use of biomass waste, specifically orange waste, for producing high-performance carbon electrodes for CDI. Biomass conversion into high-value carbon materials is an economically and environmentally viable way to produce electrodes. The activation process, utilizing potassium hydroxide (KOH), was optimized to create a carbon material with a highly developed porous structure with a large surface area and superior ion electrosorption capacity. The activated electrodes achieved a surface area of 1415 m² g⁻¹ and a salt adsorption capacity (SAC) of 15.65 mg g⁻¹. This research highlights the potential for converting agricultural and citrus processing waste into valuable materials for clean water applications. It emphasizes the importance of selecting the appropriate activating agent to modify the carbon structure and surface chemistry. The findings of this study will contribute to the way for sustainable and cost-effective advancements in CDI technology by utilizing biomass waste, potentially transforming the water desalination industry while minimizing environmental impact.
