Compared with other pretreatment methods, MSPE is simple, time-saving, and cost-effective. Furthermore, compared with traditional adsorbents, Fe3O4@FeMgAl-LDH is easy to synthesize and easily dissolves by acid. To harness this characteristic, H2SO4 was used to dissolve the Fe3O4@FeMgAl-LDH material during the extraction process instead of traditional organic solvent extraction. Thus, the extraction process was efficient and environmentally friendly. By optimizing the factors affecting extraction efficiency, an MSPE-HPLC-UV method was established under optimal conditions for the determination of four quinoline carboxylic acid antibiotics. This method offered the advantages of a wide linear range (0.077–7.000 μg·g–1), low detection limit (0.023–0.036 μg·g–1), high coefficient of determination (>0.9988), good precision (4.330–9.318%), and high extraction recovery rate (83.792–104.277%). The study findings show that this method is green and trustworthy for detecting quinoline carboxylic acid antibiotics in honey samples.","PeriodicalId":522243,"journal":{"name":"Figshare","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147894036","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
