Among the previously reported instrumental methods, the best method can only be used to determine at most 22 sulfonamides. Thus, an instrumental method capable of determining more sulfonamide species is desirable.<\/jats:p><\/jats:sec><jats:sec><jats:title>RESULTS<\/jats:title><jats:p>In this study, sulfadoxine was used as a template to synthesize a type of magnetic molecularly imprinted polymer that could recognize 35 sulfonamides. After characterization, this composite was used to develop a dispersive solid\u2010phase extraction method for extraction and purification of the 35 sulfonamides in pork, followed by determination using an ultra\u2010performance liquid chromatography photodiode array method. This composite exhibited high adsorption capacity (11.01\u201319.21\u2009\u03bcg\u2009mg<jats:sup>\u22121<\/jats:sup>) and high recovery (&gt;89.01%), and could be reused at least ten times. Due to the enrichment effect during sample preparation (enrichment factor 22\u201366), the limits of detection for determination of the 35 drugs in pork were in the range of 0.08\u20130.53\u2009ng\u2009g<jats:sup>\u22121<\/jats:sup>. The detection results for some real pork samples were consistent with a liquid chromatographic\u2013tandem mass spectrometric method. After comparison, the present method showed generally better performances than the previously reported sample preparation methods and instrumental methods for detection of sulfonamides.<\/jats:p><\/jats:sec><jats:sec><jats:title>CONCLUSION<\/jats:title><jats:p>The method developed in the present study could be used as a practical tool for routine detection of sulfonamide residues in pork samples. \u00a9 2022 Society of Chemical Industry.<\/jats:p><\/jats:sec>","DOI":"10.1002\/jsfa.12324","type":"journal-article","created":{"date-parts":[[2022,11,8]],"date-time":"2022-11-08T21:36:50Z","timestamp":1667943410000},"page":"1954-1963","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Determination of 35 sulfonamides in pork by magnetic molecularly imprinted polymer\u2010based dispersive solid\u2010phase extraction and ultra\u2010performance liquid chromatography photodiode array method"],"prefix":"10.1002","volume":"103","author":[{"given":"Su Han","family":"Wang","sequence":"first","affiliation":[{"name":"College of Veterinary Medicine Hebei Agricultural University  Baoding Hebei China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2112-0218","authenticated-orcid":false,"given":"Jian Ping","family":"Wang","sequence":"additional","affiliation":[{"name":"College of Veterinary Medicine Hebei Agricultural University  Baoding Hebei China"},{"name":"Veterinary Biological Technology Innovation Center of Hebei Province  Baoding Hebei China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ning Peng","family":"Wu","sequence":"additional","affiliation":[{"name":"Henan Institute of Veterinary Drug and Feed Control  Zhengzhou Henan China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2022,11,18]]},"reference":[{"key":"e_1_2_8_2_1","unstructured":"Ministry of Agriculture of China.National food safetystandard\u2010 maximum residue limits for veterinary drugsin foods.2019 GB31650\u20102019."},{"key":"e_1_2_8_3_1","first-page":"63","article-title":"On pharmacologicallyactive substances and their classification regarding maximum residue limits in foodstuffs ofanimal origin","volume":"15","author":"Commission regulation (EU) No 37\/2010 of 22 December 2009","year":"2010","journal-title":"Off J Eur Union"},{"key":"e_1_2_8_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.aca.2014.08.023"},{"key":"e_1_2_8_5_1","first-page":"2662","article-title":"Review of immunoassay methods for the detection of sulfonamides","volume":"21","author":"Zhang F","year":"2017","journal-title":"Curr Org Chem"},{"key":"e_1_2_8_6_1","doi-asserted-by":"publisher","DOI":"10.1021\/acs.jafc.7b03190"},{"key":"e_1_2_8_7_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.foodchem.2019.125966"},{"key":"e_1_2_8_8_1","doi-asserted-by":"publisher","DOI":"10.1021\/acs.jafc.1c05674"},{"key":"e_1_2_8_9_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.chroma.2014.04.028"},{"key":"e_1_2_8_10_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.foodchem.2015.06.093"},{"key":"e_1_2_8_11_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.aca.2018.11.005"},{"key":"e_1_2_8_12_1","first-page":"1","article-title":"Determination of antibiotics in meat samples using analytical methodologies: a review","author":"Moga A","year":"2021","journal-title":"Compr Rev Food Sci Food Saf"},{"key":"e_1_2_8_13_1","first-page":"226","article-title":"Dispersive micro\u2010solid phaseextraction.
