Among drugs, antibiotics have a significant place due to their wide consumption in veterinary and human medicine to prevent and treat microbial infections. In spite of low amounts of antibiotics in the aquatic environments, the repeated incidence of antibiotics has been caused bacterial persistence and adverse effects on health human and aquatic life. Current article evaluated the removal of metronidazole (MNZ) via heterogeneous electro-Fenton (EF) process by nano-FeO. The response surface methodology (RSM) on Box-Behnken design was applied for modeling and optimization experimental factors such as pH, applied current, and catalyst load. The efficiency of the EF process was maximum (92.26%) under the optimal condition for MNZ removal i.e. 70 mg/L of initial MNZ concentration, pH of 3, 200 mA applied current, 30 min time and 3.2 kWh/m of energy consumption.
在药物中，抗生素由于在兽医和人类医学中广泛用于预防和治疗微生物感染而占据重要地位。尽管水生环境中的抗生素含量较低，但抗生素的反复出现已导致细菌持续存在，并对人类健康和水生生物产生不利影响。当前文章评估了通过纳米FeO的非均相电芬顿（EF）工艺去除甲硝唑（MNZ）的情况。采用Box-Behnken设计的响应面方法（RSM）对pH、施加电流和催化剂负载等实验因素进行建模和优化。在去除MNZ的最佳条件下，即初始MNZ浓度为70mg/L、pH为3、施加电流为200mA、时间为30分钟且能耗为3.2kWh/m时，EF工艺的效率最高（92.26%）。
