| Tóm tắt: | The study indicates efficiency of antibiotics: Amoxicillin (AMX) and ciprofloxacin (CIP) removal in hospital wastewater using H2O2/S2O82-/ZVI process. Application of Box – Behnken design was to determine the experiment's effects on COD removal. Effect of pH, H2O2, S2O82-, ZVI and reaction time as independent variables in batch oxidation experiments, namely quadratic response. The predicted value of COD removal at optimum conditions (pH=5, [H2O2]=14.90 µg/L, [S2O82-]=50 mg/L, ZVI=40 mg/L and reaction times: 42.92 min) were 84.97%±1.6%. The AMX and CIP removal efficiencies were 99.95% and 99.90% within 42.92 minutes, while 47.60% COD occurred within 120 minutes. As a consequence, H2O2/S2O82-/ZVI process is an efficient and emerging method for removing antibiotics in hospital wastewater. |
