Abstract

Phytic acid-functionalized bamboo biochar (BC-400-PO₄) achieves exceptional U(VI) adsorption capacity (624.81 mg/g) at pH 6 within 240 min. The material demonstrates outstanding reusability, retaining 91% efficiency over five cycles. Practical validation via fixed-bed column tests confirms its efficacy: 120 mg BC-400-PO₄ reduces uranium concentrations from 0.456 mg/L to 0.082 mg/L across 8 L of actual wastewater. This work establishes sustainable bamboo-derived biochar as a high-performance adsorbent for nuclear effluent remediation, showcasing strong potential for real-world implementation.

植酸功能化竹基多孔生物炭对放射性废水中铀（VI）的高效可回收去除

植酸官能化竹生物炭（bc -400- po_4）在pH为6的条件下，在240 min内达到了624.81 mg/g的U（VI）吸附能力。该材料具有出色的可重复使用性，在五个循环中保持91%的效率。通过固定床柱试验的实际验证证实了其有效性：120 mg BC-400-PO4在8 L实际废水中将铀浓度从0.456 mg/L降至0.082 mg/L。这项工作建立了可持续的竹源生物炭作为核废水修复的高性能吸附剂，展示了在现实世界中实施的强大潜力。
