TpBD@MIL\u201068 has the unique characteristics of a covalent organic framework and a metal\u2013organic framework. TpBD@MIL\u201068 exhibited a higher extraction efficiency because of \u03c0\u2013\u03c0 and electrostatic interactions between the benzene ring structure of the TpBD, MIL\u201068, and the ultraviolet absorber molecules. The extraction conditions, including the adsorbent dosage, eluent type and dosage, elution time, and the pH of the sample solution, were fully optimized. The extraction efficiency of TpBD@MIL\u201068 exceeded 80%. The detection results showed good linearity over a wide range of concentrations (5\u20135000 \u00b5g\/L) and low detection limits (0.61\u20130.94\u00a0ng\/mL) for target molecules. The practicability of this solid\u2010phase extraction (SPE)\u2013HPLC method was further evaluated by analyzing greenhouse films and soils, with target recoveries of 80.9%\u2013109.9% and relative standard deviations of less than 8.9%. The as\u2010synthesized TpBD@MIL\u201068 adsorbent exhibited great potential in ultraviolet absorber analysis.<\/jats:p>","DOI":"10.1002\/jssc.70186","type":"journal-article","created":{"date-parts":[[2025,6,6]],"date-time":"2025-06-06T03:21:07Z","timestamp":1749180067000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Covalent\/Metal\u2013Organic Skeleton Composites for Solid\u2010Phase Extraction of Ultraviolet Absorbers in Environmental Samples"],"prefix":"10.1002","volume":"48","author":[{"given":"Mengxi","family":"Li","sequence":"first","affiliation":[{"name":"College of Chemistry Beijing Key Laboratory of Environmentally Harmful Chemical Analysis Beijing University of Chemical Technology  Beijing People's Republic of China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xinrui","family":"Tian","sequence":"additional","affiliation":[{"name":"College of Chemistry Beijing Key Laboratory of Environmentally Harmful Chemical Analysis Beijing University of Chemical Technology  Beijing People's Republic of China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jiayi","family":"Song","sequence":"additional","affiliation":[{"name":"College of Chemistry Beijing Key Laboratory of Environmentally Harmful Chemical Analysis Beijing University of Chemical Technology  Beijing People's Republic of China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ping","family":"Su","sequence":"additional","affiliation":[{"name":"College of Chemistry Beijing Key Laboratory of Environmentally Harmful Chemical Analysis Beijing University of Chemical Technology  Beijing People's Republic of China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4091-8532","authenticated-orcid":false,"given":"Yi","family":"Yang","sequence":"additional","affiliation":[{"name":"College of Chemistry Beijing Key Laboratory of Environmentally Harmful Chemical Analysis Beijing University of Chemical Technology  Beijing People's Republic of China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2025,6,6]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1002\/(SICI)1097-4628(19980808)69:6<1251::AID-APP20>3.0.CO;2-U"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.1002\/jssc.201100448"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.chroma.2019.460793"},{"key":"e_1_2_7_5_1","doi-asserted-by":"publisher","DOI":"10.1007\/s10337-015-2988-6"},{"issue":"1","key":"e_1_2_7_6_1","article-title":"Dispersive Liquid\u2010Liquid Microextraction (DLLME) and External Real Matrix Calibration for the Determination of the UV Absorber 2\u2010(2H\u2010Benzotriazol\u20102\u2010yl)\u20104,6\u2010Di\u2010Tert\u2010Pentylphenol (UV 328) and Its Metabolites in Human Blood","volume":"223","author":"Heike D.","year":"2021","journal-title":"Talanta"},{"key":"e_1_2_7_7_1","doi-asserted-by":"publisher","DOI":"10.1021\/es902536u"},{"key":"e_1_2_7_8_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.envpol.2022.120935"},{"key":"e_1_2_7_9_1","first-page":"97","article-title":"Multi\u2010Target Determination of Organic Ultraviolet Absorbents in Organism Tissues by Ultrasonic Assisted Extraction and Ultra\u2010High Performance Liquid Chromatography\u2013Tandem Mass Spectrometry","volume":"2015","author":"Peng X.
