Abstract
Uranium-containing wastewater from the nuclear fuel cycle poses severe hazards to human health and the environment. In this study, a carboxylated multi-walled carbon nanotube/copper oxide/nano silver modified graphite felt electrode (MCA) material was designed, exhibiting electrosorption performance with electrical double layer and pseudocapacitance characteristics. Electrosorption processes proved the ability to adsorb U(VI). MCA-2 had the highest removal rate (93.31%) due to superior conductivity, stability, and capacitance characteristics. A high adsorption capacity of 361 mg/g was reached in a 200 mg/L U(VI) solution. MCA achieves good cycling stability and high selectivity, making it a potential electrode material for radioactive wastewater treatment.
