摘要

盐酸环丙沙星（CFX）是一种广泛用于细菌感染的抗生素，研究人员通过应用高级氧化工艺（AOPs），包括水动力空化（HC）、臭氧氧化（O3）、芬顿反应、化学氧化以及 HC/O3 和 Fenton/O3 等混合 AOPs，对其进行了降解研究。其中，在初始浓度为 1000 ppm 的情况下，HC/O3 混合组合在 180 分钟内对 CFX 的降解率最高，达到 99.82%。通过改变初始浓度、pH 值、臭氧（O3）气体流量和温度等参数，对 HC/O3 工艺进行了优化。在整个降解过程中，CFX 会形成中间产物，并随着时间的推移逐渐降解。

Enhanced Degradation of Ciprofloxacin Hydrochloride Using Hybrid Advanced Oxidation Process of Hydrodynamic Cavitation and Ozonation

The degradation of ciprofloxacin hydrochloride (CFX), an extensively utilized antibiotic for bacterial infections, has been studied through the application of advanced oxidation processes (AOPs) including hydrodynamic cavitation (HC), ozonation (O₃), the Fenton reaction, chemical oxidation, and hybrid AOPs such as HC/O₃ and Fenton/O₃. Among these, the hybrid combination of HC/O₃ demonstrated the highest CFX degradation of 99.82 % within 180 min having an initial concentration of 1000 ppm. The optimization of the HC/O₃ process was conducted by varying parameters including initial concentration, pH, ozone (O₃) gas flowrate, and temperature. Throughout the degradation process, CFX underwent intermediate formation, which gradually degraded over time.
