To advance the application of Cu-metal–organic framework (Cu-MOF) in uranium wastewater treatment for the nuclear industry, it is essential to address the limitations of its powder form and rigid structure while enhancing its adsorption capacity. In this study, a Cu-MOF@CSTA composite adsorbent was synthesized by solidifying Cu-MOF with chitosan/tannic acid and modifying its functional groups to improve uranium adsorption performance. The U(VI) theoretical maximum adsorption capacity of Cu-MOF@CSTA at 288 K (pH = 5) was 2507.73 mg/g, and the...
