The extraction\/concentration and recovery degree of these dyes from liquid matrices were done on Strata WAX\/NH2 cartridges. The chromatographic separation was performed using a Luna C18 (2) 100\u00c5 column by isocratic elution with a methanol\u2013acetonitrile\u2013water (0.2% formic acid and 2 mM ammonium formate) mixture. The linearity, the LOD, and the LOQ were determined for each textile dye. The accuracy, the precision (intra- and inter-day), and the matrix effect were also performed for the validation of the developed procedure. These chromium-complex azo dyes often used in the dyeing process by a textile factory in Romania were monitored in the influent and effluent wastewater from a treatment plant situated in its area. Applying the developed SPE-LC-ESI(\u2013)-MS\/MS procedure, the following textile dyes were detected (ng\/L) in the collected wastewater samples during a 24-h period: NDB 150.1, LDB 200.6, and LR 89.0\u2013244.0 in influents and NDB 22.8, LDB 78.6, and LR 74.0 in effluents.<\/jats:p>","DOI":"10.5740\/jaoacint.18-0059","type":"journal-article","created":{"date-parts":[[2018,5,19]],"date-time":"2018-05-19T01:11:37Z","timestamp":1526692297000},"page":"1422-1428","source":"Crossref","is-referenced-by-count":1,"title":["Determination of Three Chromium Textile Azo Dyes in Wastewater by SPE-LC-ESI(\u2013)-MS\/MS"],"prefix":"10.1093","volume":"101","author":[{"given":"Florina-Maria","family":"Copaciu","sequence":"first","affiliation":[{"name":"Babe\u015f-Bolyai University, \u201cRaluca Ripan\u201d Institute for Research in Chemistry, 30 F\u00e2nt\u00e2nele St, Cluj-Napoca, Romania, 400294"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dorina","family":"Simedru","sequence":"additional","affiliation":[{"name":"INCDO-INOE 2000, Research Institute for Analytical Instrumentation, 67 Donath St, Cluj-Napoca, Romania, 400293"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Maria-Virginia","family":"Coman","sequence":"additional","affiliation":[{"name":"Babe\u015f-Bolyai University, \u201cRaluca Ripan\u201d Institute for Research in Chemistry, 30 F\u00e2nt\u00e2nele St, Cluj-Napoca, Romania, 400294"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2019,11,23]]},"container-title":["Journal of AOAC INTERNATIONAL"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/academic.oup.com\/jaoac\/article-pdf\/101\/5\/1422\/32426903\/jaoac1422.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"syndication"},{"URL":"http:\/\/academic.oup.com\/jaoac\/article-pdf\/101\/5\/1422\/32426903\/jaoac1422.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2020,7,17]],"date-time":"2020-07-17T16:43:18Z","timestamp":1595004198000},"score":1,"resource":{"primary":{"URL":"https:\/\/academic.oup.com\/jaoac\/article\/101\/5\/1422\/5654078"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2018,9,1]]},"references-count":0,"journal-issue":{"issue":"5","published-online":{"date-parts":[[2019,11,23]]},"published-print":{"date-parts":[[2018,9,1]]}},"URL":"https:\/\/doi.org\/10.5740\/jaoacint.18-0059","relation":{},"ISSN":["1060-3271","1944-7922"],"issn-type":[{"value":"1060-3271","type":"print"},{"value":"1944-7922","type":"electronic"}],"subject":[],"published-other":{"date-parts":[[2018,9,1]]},"published":{"date-parts":[[2018,9,1]]}}}
