关键字：Halogen wastewater greatly threatens the health of human beings and aquatic livings due to its severe toxicity, corrosiveness, and volatility. Efficient bromine removal is therefore urgently required, while existing Br2-capture materials often face challenges from limited water stability and possible halogen leaking. We report a facile and efficient aqueous Br2 removal method using sub-micron resorcinol-formaldehyde (RF) resin nanoparticles (NPs). Its abundant aromatic groups dominate the Br2 removal by substitution reactions. An excellent Br2 conversion capacity of 7441 mg g-1RF was achieved by RF NPs that outperforms state-of-the-art materials by ~2 folds, along with advantages including good water stability, low cost and easy fabrication. Two recycling-coupled (electrochemical or H2O2-involved) Br2 removal routes further reveal the feasibility of in-depth halogen removal by RF NPs. The brominated resin can be downstream upcycled for selective silver recovery, realizing the harvesting of precious metal, reducing of heavy-metal pollution and resource utilization of brominated resin.
