在这项研究中，研究了使用碳纳米管（CNT）电化学过滤器和4-epianhydrochlortetracycline（EACTC）作为模型化合物对四环素水解产物的电氧化作用。在2.5 V电压和1.5 mL min-1的流速（液压停留时间<3 s）下对10μmolL-1 EACTC进行电化学过滤，氧化通量为1251±28μmolh-1 m-2。在2.5 V电压下，用CNT过滤阴极替换Ti阴极可使EACTC的氧化通量增加1.3倍。电化学过滤过程对于EACTC的降解和基于液相色谱时间的抗菌活性的降低是有效的。飞行质谱（LC-TOF-MS）分析和发光细菌测试。300分钟内的高氧化通量（1212-1263μmolh-1 m-2）和可承受的成本（0。在2.5 V电压下的25 kWh m-3）显示了电化学过滤系统作为EACTC降解的有希望的单元的潜在应用。这些发现为旨在有效去除抗生素四环素水解产物的新型连续流过滤系统的合理设计原理提供了新见解。
