Abstract

Nuclear energy is an essential part of the global energy mix, and its sustainable development relies on efficient and selective uranium extraction technologies. This study presents a 2-phosphonate butane 1, 2, 4-tricarboxylic acid (PBTCA)-modified self-crosslinked chitosan gel as a novel adsorbent for uranium extraction from wastewater. At an optimized voltage of −0.6 V, the material exhibited an impressive adsorption capacity of 631.94 mg·g⁻¹, along with excellent electrochemical performance and cycling stability. This innovative material, characterized by low energy consumption, high adsorption efficiency, and excellent regeneration capability, provides a promising solution for uranium recovery. This work highlights the potential of targeted chemical modifications in enhancing polymer-based electrosorption technologies.
