Doxycycline Degradation by the Oxidative Fenton Process by Alexandre A. Borghi, Milena F. Silva, Saleh Al Arni, Attilio Converti, Mauri S. A. Palma

“…Experiments were performed according to an experimental Rotational Central Composite Design to investigate the influence of temperature (0–40.0°C), H2O2 concentration (100–900 mg/L), and Fe2+ concentration (5–120 mg/L) on residual doxycycline and total organic carbon concentrations. Whereas the final residual doxycycline concentration ranged from 0 to 55.8 mg/L, the oxidation process proved unable to reduce the total organic carbon by more than 30%. …”
