A series of experiments were conducted to obtain the optimal TD conditions. The results indicated that the optimal TD parameters were as follows: desorption temperature of 180\u00b0C, desorption flow rate of 50\u2009mL\u2009min\u22121, and desorption time of 30\u2009min. Furthermore, the method based on UiO-66 enrichment integrated with TD-GC-MS for trace levels of BTX was successfully developed. It exhibited a good linearity (R2\u2009&gt;\u20090.99) in the range of 50\u20131000\u2009ng, except for p, m-xylene in the range of 100\u20132000\u2009ng, and achieved the recovery of 69.4\u2013101.3%, and the relative standard deviation of 3.8\u20136.4%. The detection limits of BTX were 1.6\u20134.0\u2009ng; according to 10\u2009L of sampling volume, the method detection limits would be in the range of 0.16\u20130.40\u2009\u00b5g m\u22123. Additionally, the method was successfully applied to determine BTX in indoor air and showed good selectivity and sensitivity. In summary, the findings in this work revealed that UiO-66 was an attractive adsorbent for selective enrichment trace levels of BTX compounds in ambient air, which was favorable for the subsequent detection by TD-GC-MS.<\/jats:p>","DOI":"10.1155\/2021\/3138436","type":"journal-article","created":{"date-parts":[[2021,12,14]],"date-time":"2021-12-14T17:50:08Z","timestamp":1639504208000},"page":"1-9","source":"Crossref","is-referenced-by-count":7,"title":["UiO-66 Selective Enrichment Integrated with Thermal Desorption GC-MS for Detection of Benzene Homologues in Ambient Air"],"prefix":"10.1155","volume":"2021","author":[{"given":"Xing-Tao","family":"Lin","sequence":"first","affiliation":[{"name":"Faculty of Environment and Life, Beijing University of Technology, Beijing 100124, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ge","family":"Sun","sequence":"additional","affiliation":[{"name":"Faculty of Environment and Life, Beijing University of Technology, Beijing 100124, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jing-Qiang","family":"Zhao","sequence":"additional","affiliation":[{"name":"Faculty of Environment and Life, Beijing University of Technology, Beijing 100124, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ling-Li","family":"Tang","sequence":"additional","affiliation":[{"name":"Faculty of Environment and Life, Beijing University of Technology, Beijing 100124, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sheng-Hua","family":"Li","sequence":"additional","affiliation":[{"name":"School of Materials Science and Engineering, Beijing Institute of Technology, Beijing 100081, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2879-3036","authenticated-orcid":true,"given":"Ya-Bo","family":"Xie","sequence":"additional","affiliation":[{"name":"Faculty of Environment and Life, Beijing University of Technology, Beijing 100124, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","reference":[{"key":"1","doi-asserted-by":"publisher","DOI":"10.1021\/acs.est.6b04509"},{"key":"2","doi-asserted-by":"publisher","DOI":"10.1016\/j.chemosphere.2017.02.105"},{"key":"3","doi-asserted-by":"publisher","DOI":"10.1007\/s11869-019-00664-1"},{"key":"4","doi-asserted-by":"publisher","DOI":"10.1016\/s1001-0742(11)60735-3"},{"key":"5","volume-title":"WHO Guidelines for Indoor Air Quality: Selected Pollutants","author":"WHO","year":"2010"},{"key":"6","volume-title":"Inspectioin and Quarantine of the People\u2019s Republic of China","author":"General Administration of Quality Supervision","year":"2002"},{"key":"7","doi-asserted-by":"publisher","DOI":"10.1007\/s12274-016-1230-7"},{"key":"8","doi-asserted-by":"publisher","DOI":"10.1016\/j.scitotenv.2009.09.026"},{"key":"9","doi-asserted-by":"publisher","DOI":"10.1007\/s11869-014-0254-y"},{"key":"10","doi-asserted-by":"publisher","DOI":"10.1007\/s00216-002-1352-5"},{"key":"11","doi-asserted-by":"publisher","DOI":"10.1038\/srep27813"},{"key":"12","doi-asserted-by":"publisher","DOI":"10.1039\/c5cs00837a"},{"key":"13","doi-asserted-by":"publisher","DOI":"10.1021\/cr300014x"},{"key":"14","doi-asserted-by":"publisher","DOI":"10.1021\/cr200190s"},{"key":"15","doi-asserted-by":"publisher","DOI":"10.1002\/jssc.201800119"},{"key":"16","doi-asserted-by":"publisher","DOI":"10.1039\/c8ta04539a"},{"key":"17","doi-asserted-by":"publisher","DOI":"10.1002\/adma.201704679"},{"key":"18","doi-asserted-by":"publisher","DOI":"10.1021\/jacs.9b00733"},{"key":"19","doi-asserted-by":"crossref","first-page":"321","DOI":"10.1016\/j.jes.2016.09.017","article-title":"Development of metal organic framework-199 immobilized zeolite foam for adsorption of common indoor VOCs","volume":"55","author":"V.
