Ofloxacin (OFX), commonly employed in the treatment of infectious diseases, is frequently detected in aquatic environments and poses potential ecological risks. UV/HO oxidation has been recognized as an efficient approach for removing antibiotics. In this study, Cu-doped waste-tire carbon was prepared and used as a UV/HO catalyst for the degradation of OFX. The results showed that the OFX removal was 89.3% within 90 min under the optimal reaction conditions. It was found that ZnO, used in the tire manufacturing to promote rubber vulcanization for enhanced stability and durability, played an important role in UV/H₂O₂ oxidation for OFX degradation. Toxicity experiments conducted with a microbial degradation respirometer demonstrated that the treated water exhibited low toxicity. This study introduces a sustainable catalyst derived from waste tires, and facilitating the development of metal-carbon catalysts for the effective removal of antibiotics from wastewater.
氧氟沙星（OFX）常用于治疗传染病，在水环境中经常被检测到，并带来潜在的生态风险。紫外/过氧化氢（UV/HO）氧化已被认为是去除抗生素的有效方法。在本研究中，制备了铜掺杂废轮胎炭，并将其用作UV/HO催化剂来降解OFX。结果表明，在最佳反应条件下，90分钟内OFX的去除率为89.3%。研究发现，用于轮胎制造以促进橡胶硫化从而提高稳定性和耐久性的氧化锌，在UV/H₂O₂氧化降解OFX过程中发挥了重要作用。使用微生物降解呼吸仪进行的毒性实验表明，处理后的水毒性较低。本研究引入了一种源自废轮胎的可持续催化剂，并推动了用于有效去除废水中抗生素的金属-碳催化剂的发展。
