In this study, a ternary covalent organic polymer anchored with SO3H (COP-SO3H) was designed using the Schiff reaction and a multicomponent solvent thermal method. The synthesized COP-SO3H polymer possesses multiple functional binding sites, including amide groups, sulfonic groups, and aromatic frameworks, enabling it to effectively adsorb ciprofloxacin (which belongs to FQs) through mechanisms such as pore-filling effects, electrostatic interactions, hydrogen bonding, \u03c0-\u03c0 electron donor\u2013acceptor (EDA) interactions, and hydrophilic\u2013lipophilic balance. COP-SO3H demonstrated outstanding adsorption performance for ciprofloxacin, exhibiting a high adsorption capacity, broad pH stability, strong resistance to ionic interference, and good regenerability. Moreover, it displayed preferential selectivity toward fluoroquinolone antibiotics. The present study not only investigates the intricate structural and functional design of COP-SO3H materials but also presents potential applications for the efficient adsorption of specific antibiotics.<\/jats:p>","DOI":"10.3390\/molecules28196941","type":"journal-article","created":{"date-parts":[[2023,10,6]],"date-time":"2023-10-06T01:07:13Z","timestamp":1696554433000},"page":"6941","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["Adsorption Behavior of a Ternary Covalent Organic Polymer Anchored with SO3H for Ciprofloxacin"],"prefix":"10.3390","volume":"28","author":[{"given":"Zhuoran","family":"Wang","sequence":"first","affiliation":[{"name":"Key Laboratory of Groundwater Resources and Environment of Ministry of Education, College of New Energy and Environment, Jilin University, Changchun 130021, China"},{"name":"Jilin Provincial Key Laboratory of Water Resources and Environment, College of New Energy and Environment, Jilin University, Changchun 130021, China"},{"name":"National and Local Joint Engineering Laboratory for Petrochemical Contaminated Site Control and Remediation Technology, Jilin University, Changchun 130021, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chuanyu","family":"Qin","sequence":"additional","affiliation":[{"name":"Key Laboratory of Groundwater Resources and Environment of Ministry of Education, College of New Energy and Environment, Jilin University, Changchun 130021, China"},{"name":"Jilin Provincial Key Laboratory of Water Resources and Environment, College of New Energy and Environment, Jilin University, Changchun 130021, China"},{"name":"National and Local Joint Engineering Laboratory for Petrochemical Contaminated Site Control and Remediation Technology, Jilin University, Changchun 130021, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dongyu","family":"Zhao","sequence":"additional","affiliation":[{"name":"Key Laboratory of Groundwater Resources and Environment of Ministry of Education, College of New Energy and Environment, Jilin University, Changchun 130021, China"},{"name":"Jilin Provincial Key Laboratory of Water Resources and Environment, College of New Energy and Environment, Jilin University, Changchun 130021, China"},{"name":"National and Local Joint Engineering Laboratory for Petrochemical Contaminated Site Control and Remediation Technology, Jilin University, Changchun 130021, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ziheng","family":"Wang","sequence":"additional","affiliation":[{"name":"Key Laboratory of Groundwater Resources and Environment of Ministry of Education, College of New Energy and Environment, Jilin University, Changchun 130021, China"},{"name":"Jilin Provincial Key Laboratory of Water Resources and Environment, College of New Energy and Environment, Jilin University, Changchun 130021, China"},{"name":"National and Local Joint Engineering Laboratory for Petrochemical Contaminated Site Control and Remediation Technology, Jilin University, Changchun 130021, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dongpeng","family":"Mao","sequence":"additional","affiliation":[{"name":"Key Laboratory of Groundwater Resources and Environment of Ministry of Education, College of New Energy and Environment, Jilin University, Changchun 130021, China"},{"name":"Jilin Provincial Key Laboratory of Water Resources and Environment, College of New Energy and Environment, Jilin University, Changchun 130021, China"},{"name":"National and Local Joint Engineering Laboratory for Petrochemical Contaminated Site Control and Remediation Technology, Jilin University, Changchun 130021, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,10,5]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Ezelarab, H.A.A., Abbas, S.H., Hassan, H.A., and Abuo-Rahma, G.E.A.
