Present study investigates the potential of Ti/RuO₂ electrode for degradation and mineralization of Ofloxacin (OFLX) antibiotic from synthetic wastewater by electro-oxidation (EO) method, not reported earlier. Effects of various EO parameters such as applied current (I), initial pH, initial OFLX concentration (C₀) and supporting electrolyte concentration on %OFLX removal efficiency and %TOC removal efficiency were systematically studied and reported. Decay kinetics of OFLX by varying C₀ and applied I were also studied. Additionally, Mineralization current efficiency and specific energy consumption of OFLX mineralization were evaluated. Moreover, mode of oxidation method involved (direct and/or indirect oxidation) was also explored. Major OFLX transformation products during EO were identified using UPLC-Q-TOF-MS, and possible degradation reaction mechanism was proposed. Furthermore, operating cost analysis was performed to check the economic feasibility of the EO process.

The optimum pH and current were found to be 6.8 (natural pH of OFLX wastewater) and 1 A, respectively. Mineralization current efficiency decreased from 7.8% to 4.9% with increase in I value from 0.25 to 1 A. ≈80% of OFLX removal in 30 min of electrolysis and 46.3% TOC removal in 240 min of electrolysis at I = 1 A were observed. Pseudo-first-order kinetic model best fitted the experimental data showing R² value ≈ 0.99 for all the C_o and applied I studied.

本研究通过电氧化（EO）方法研究了Ti / RuO ₂电极对合成废水中氧氟沙星（OFLX）抗生素的降解和矿化的潜力，目前尚未见报道。系统地研究和报道了各种EO参数，例如施加电流（I），初始pH，初始OFLX浓度（C ₀）和辅助电解质浓度对％OFLX去除效率和％TOC去除效率的影响。通过改变C _0来降低OFLX的动力学并应用了我也进行了研究。此外，还评估了OFLX矿化的矿化电流效率和比能耗。此外，还探讨了所涉及的氧化方法的模式（直接和/或间接氧化）。利用UPLC-Q-TOF-MS鉴定了EO中主要的OFLX转化产物，并提出了可能的降解反应机理。此外，进行了运营成本分析以检查EO工艺的经济可行性。

发现最佳pH和电流分别为6.8（OFLX废水的自然pH）和1A。随着I值从0.25 A增加到1 A，矿化电流效率从7.8％降低到4.9％。在I = 1 A的条件下，在电解30分钟内可去除≈80％的OFLX和在240分钟电解中可去除46.3％的TOC。伪一阶动力学模型最适合于所有C _o的R ²值≈0.99的实验数据，并且我进行了研究。
