开发高效、环境友好型的技术并应用于抗菌药污染水体的修复是现今热点。研究发现，在降解过程中部分典型氟喹诺酮抗菌药（FQs）会转化成为市场在售的、与其母体结构相似且具有生态风险的物质（产物FQs）。本课题拟利用新型苝酰亚胺（PDI）超分子材料在阳光下降解FQs污染物，重点剖析“FQs-产物FQs”转化机制。研究内容包括：建立典型FQs的SPE-LC/MS/MS分析方法；确定FQs与产物FQs的动力学行为关系；揭示活性物种对“FQs-产物FQs”转化的作用规律；评估母体FQs、产物FQs和反应液的抑菌活性并提出降低FQs处理液生态风险的条件。研究成果将为PDI/阳光催化体系应用于典型水体中FQs的污染修复提供理论基础和技术支撑；同时，将进一步阐明FQs的环境归趋。

Developing an efficient, environmental-friendly technology and conducting the application to antimicrobial contamination remediation in water is a hot spot. Previous studies have found that some of the typical fluoroquinolone antibacterial (FQs) can produce the substances that are commercially available, similar maternal structures and potentially ecologically risky (product FQs). The present study plans to investigate the transformation mechanism of “FQs-product FQs” by using a novel perylene diimide (PDI) supramolecular material under sunlight irradiation. The research contents include the establishment of the SPE-LC/MS/MS analysis method for FQs, elucidating the kinetics behavior relation of FQs and product FQs, revealing the action rule of reactive species for the transformation of “FQs-product FQs”. Further, the ecological risks of maternal FQs, product FQs and reaction solutions were evaluated, and finally the conditions to reduce the ecological risk of FQs were proposed. The results will provide theoretical basis and technical support for the FQs remediation in typical water. Simultaneously, the fate of FQs will be further illuminated.
