Key Findings in This Report

• • Cell voltage reduced to 0.6 V, significantly lower than conventional EUE systems, minimizing side reactions and energy consumption. • • Simultaneous uranium extraction at both anode and cathode via Cu(0)/Cu(I) redox chemistry and Cu2(OH)3Cl formation, enhancing overall extraction efficiency. • • Long-term stability demonstrated in small-scale seawater tests, with selectivity for uranium over competing ions in high-salinity environments. • • Energy consumption outperforms reported traditional EUE systems, providing a viable route for industrial-scale seawater uranium extraction.
