The operating conditions and reaction mechanism of the Ce-Ni@WSA catalytic ozonation of norfloxacin (Nor) simulated wastewater were systematically studied. A data-envelopment analysis model (DEA-B 2 C) was then established to evaluate the catalytic ozonation process. Under the optimal conditions of initial pH 7.42 (raw water), ozone dosage = 0.4 g/L/h, catalyst filling ratio = 5%, humic acid dosage = 0 mg/L, the removal rates of COD and Nor reached 84.95% and 93.52%, respectively. Ce-Ni@WSA retained its high catalytic performance and mechanical strength after repeated use. Mechanistic studies showed that ·OH oxidation was dominant in the catalytic-ozonation system, and Nor can be degraded into small molecules through three different pathways and eventually mineralized. The DEA-B 2 C model analysis showed that the treatment cost was low and the catalytic efficiency was high under the optimal operating conditions. ozone catalyst catalytic oxidation norfloxacin silica-alumina gel model analysis Full Text Additional Declarations No competing interests reported.

The operating conditions and reaction mechanism of the Ce-Ni@WSA catalytic ozonation of norfloxacin (Nor) simulated wastewater were systematically studied. A data-envelopment analysis model (DEA-B\u003csup\u003e2\u003c/sup\u003eC) was then established to evaluate the catalytic ozonation process. Under the optimal conditions of initial pH 7.42 (raw water), ozone dosage\u0026thinsp;=\u0026thinsp;0.4 g/L/h, catalyst filling ratio\u0026thinsp;=\u0026thinsp;5%, humic acid dosage\u0026thinsp;=\u0026thinsp;0 mg/L, the removal rates of COD and Nor reached 84.95% and 93.52%, respectively. Ce-Ni@WSA retained its high catalytic performance and mechanical strength after repeated use. Mechanistic studies showed that \u0026middot;OH oxidation was dominant in the catalytic-ozonation system, and Nor can be degraded into small molecules through three different pathways and eventually mineralized. The DEA-B\u003csup\u003e2\u003c/sup\u003eC model analysis showed that the treatment cost was low and the catalytic efficiency was high under the optimal operating conditions.\u003c/p\u003e","manuscriptTitle":"Performance evaluation of catalytic ozone oxidation of norfloxacin over Ce-Ni@WSA catalysts","msid":"","msnumber":"","nonDraftVersions":[{"code":1,"date":"2025-10-16 14:48:28","doi":"10.21203/rs.3.rs-7719957/v1","editorialEvents":[{"type":"communityComments","content":0}],"status":"published","journal":{"display":true,"email":"[email protected]","identity":"researchsquare","isNatureJournal":false,"hasQc":true,"allowDirectSubmit":true,"externalIdentity":"","sideBox":"","snPcode":"","submissionUrl":"/submission","title":"Research Square","twitterHandle":"researchsquare","acdcEnabled":true,"dfaEnabled":false,"editorialSystem":"","reportingPortfolio":"","inReviewEnabled":false,"inReviewRevisionsEnabled":true}}],"origin":"","ownerIdentity":"d7919151-3ad3-4431-a684-7e74c31d9d35","owner":[],"postedDate":"October 16th, 2025","published":true,"recentEditorialEvents":[],"rejectedJournal":[],"revision":"","amendment":"","status":"posted","subjectAreas":[],"tags":[],"updatedAt":"2025-11-25T22:08:46+00:00","versionOfRecord":[],"versionCreatedAt":"2025-10-16 14:48:28","video":"","vorDoi":"","vorDoiUrl":"","workflowStages":[]},"version":"v1","identity":"rs-7719957","journalConfig":"researchsquare"},"__N_SSP":true},"page":"/article/[identity]/[[...version]]","query":{"redirect":"/article/rs-7719957","identity":"rs-7719957","version":["v1"]},"buildId":"8U1c8b4HqxoKbykW_rLl7","isFallback":false,"isExperimentalCompile":false,"dynamicIds":[84888],"gssp":true,"scriptLoader":[]}
