摘要：

Developing efficient, stable, and user-friendly adsorbents for removing uranium from radioactive wastewater is critical for ensuring the security of nuclear energy development. Here, a fixed adsorbent (nZVI@NC/CF), composed of in-situ derived N-doped carbon (NC) encapsulated nano zero-valent iron (nZVI) coated on carbon fiber (CF), was synthesized via carbonizing Prussian blue decorated CF, and used to synergistically adsorb and reduce UO22+ from contaminated water. The optimized nZVI@NC/CF exhibited an extremely high adsorption capacity of 212...
