Extracting uranium from nuclear wastewater is vital for environmental and human health protection. However, despite progress in extraction, there remains a demand an optimized adsorbent with improved capability, efficiency, selectivity. To bridge this gap, 1,2,3,4-butane tetracarboxylic acid (BTCA)-modified MIL-101 was synthesized through simple hydrothermal reaction between amino-modified (MIL-101-NH2) BTCA. Density Functional Theory calculations validated the formation of stable coordination bonds hydrogen bond network, bolstering adsorption capacity. further enhance capacity, influence electric field on performance investigated. Studies revealed that uranyl ion removal under involves both electrosorption electroreduction pathways. This dual mechanism not only significantly increases capacity 221.1 mg g-1 to 331.4 but also improves efficiency. These insights our understanding effective foster development sustainable, ecofriendly technologies energy field.
