Abstract To mitigate pollution caused by levofloxacin (LVF) in aquatic environments, a magnetic catalyst, CoFe 2 O 4 /CoFe@BC (CF@BC), was synthesized using loofah‐derived biochar (BC) as support, through coprecipitation followed calcination at high temperatures. CF@BC utilized for the degradation of LVF aqueous solutions containing peroxymonosulfate (PMS), requiring no additional energy input. demonstrates exceptional catalytic performance, even under acidic conditions, achieving rate 98% within min. Compared to pure nanoparticles (CF), exhibits smaller particle sizes and improved dispersion properties, enhancing exposure reactive sites. The degradability CF@BC/PMS system is nearly three times greater than that CF/PMS identical conditions. Furthermore, demonstrated effective across wide initial pH range (3 9) maintained efficiency after cycles. Both Co(II)/Co(III) Fe(III)/Fe(II) are involved activation process PMS, with SO₄ •− 1 O₂ being predominant species contributing degradation. Additionally, two pathways have been proposed. developed this study can be effectively applied remediate water contaminated LVF.

Mn-based catalysts have been extensively studied in advanced oxidation processes based on peroxymonosulfate (PMS) oxidants, demonstrating their significant potential for treating antibiotic-contaminated wastewater. In this study, an amorphous MnO2-based composite catalyst (MnO2/CN@SiO2) was prepared and used to activate PMS degrading levofloxacin (LEV). The effects of reaction conditions, such as temperature, dosage, concentration, solution pH, LEV degradation were comprehensively investigated. interference water components, e.g., NO3−, SO42−, Cl−, CO32−, humic acid, the efficiency analyzed, stability explored by cycling experiments. Finally, radical quenching experiments electron paramagnetic resonance spectroscopy employed elucidate contribution active species process. A non-radical-based pathway proposed these results.
