Mitigating antibiotic pollution is essential to combating resistance, safeguarding ecosystems, ensuring food and water safety, preserving the efficacy of antibiotics. Simultaneously, comprehensive utilization red mud a key approach reducing resource waste ecological damage. This study investigates use iron components from prepare RM-nZVI/Ni for Fenton-like reactions, aimed at degrading antibiotics in water. By leveraging inherent content mud, was developed achieve dual-purpose environmental strategy: degradation solid recycling. The results demonstrate that 0.02 g/L sulfamethoxazole (SMX) can be fully degraded within 15 min using 0.1 6 mM H2O2. Hydroxyl radicals (·OH) Ni were identified as contributors SMX removal. Moreover, this system exhibits universality common such LFX, NFX, CIP, TC. LC-MS analysis DFT theoretical calculations indicate byproducts are lower toxicity or non-toxic. Additionally, cost suggests cost-effective efficient catalyst. research gives valuable insights into mud-based catalysts offers guidance expanding high-value applications mud.
