This study evaluates the effectiveness of iron-modified biochar (Fe-BC) in fixed-bed heterogeneous Fenton processes for levofloxacin (LFX) removal, a widely-used fluoroquinolone antibiotic. The objective is to optimize parameters such as pH, oxidants (H2O2 and S2O82−), forms (functionalized raw) using factorial analysis mixed data (FAMD) response surface methodology (RSM). These optimizations identified ideal conditions maximal LFX removal. most effective removal with Fe-BC occurred at 2.5 mM H2O2 pH 7.5, while optimal S2O82− were 1.6 2.8. Both raw (RBC) showed highest adsorption 5.8. In adsorption-only, RBC reduced 530 μg/L 335 μg/L, respectively, 60 minutes. oxidation process further decreased levels between 8.9 0.1 H2O2, respectively. research expanded upon kinetic model, incorporating calculation constants both processes, deepen our understanding intricate degradation dynamics play. Identifying by-products was crucial elucidating pathways. findings are vital environmental remediation, demonstrating efficiency removing harmful antibiotics from water. highlights potential modified clean-up, especially water contaminated antibiotics. results emphasize importance optimizing treatment antibiotic contributing valuable insights field remediation.
