Ofloxacin Degradation over Nanosized Fe3O4 Catalyst viaThermal Activation of Persulfate Ions

In this work, an Fe3O4 catalyst was synthetized in a single step via electrochemical synthesis. The used to evaluate the degradation of Ofloxacin (OFX) using heterogeneous advanced oxidation process with sodium persulfate (PS). PS activation successfully achieved thermal conventional heating directly and subsequently applied for OFX. kinetics were studied under different conditions, such as oxidant concentration temperature. results show that higher reaction temperature, initial dose strongly influence efficiency. Thermal tested at 20, 40 60 °C. At °C, half-time OFX 23 times greater than 20 confirming persulfate. Mineralization studies also showed optimized conditions (20 mM persulfate, 1 g/L 100 mg/L OFX), 66% reduction organic matter observed, contrast obtained °C which null. reusability, through fourth reuse cycle, resulted 38% reduced efficiency when comparing first last cycle. Furthermore, electrosynthesized presented similar efficiencies both real water MilliQ, mainly because Cl2? generation high Cl? concentrations takes place contaminated water.
