Pressurized liquid extraction operating conditions were optimized and maximum recoveries were reached using methanol under the following operational conditions: 100\u00baC, 1500 psi, extraction time of 5 min, one extraction cycle, flush volume of 60% and purge time of 120 s. Pressurized liquid extraction recoveries were higher than 88% for all the compounds except for carbamazepine (55%). The repeatability and reproducibility between days, expressed as relative standard deviation (<jats:italic>n<\/jats:italic>\u00a0=\u00a05), were lower than 6 and 10%, respectively. The detection limits for all compounds were lower than 12.5\u00a0\u03bcg\/kg of dry weight. The method was applied to determine benzodiazepines and barbiturates in sewage sludge from urban sewage treatment plants, and carbamazepine showed the highest concentration (7.9\u201318.9\u00a0\u03bcg\/kg dry weight).<\/jats:p>","DOI":"10.1002\/jssc.201400791","type":"journal-article","created":{"date-parts":[[2014,9,15]],"date-time":"2014-09-15T13:16:51Z","timestamp":1410787011000},"page":"3481-3488","source":"Crossref","is-referenced-by-count":9,"title":["Determination of sedative hypnotics in sewage sludge by pressurized liquid extraction with high\u2010performance liquid chromatography and tandem mass spectrometry"],"prefix":"10.1002","volume":"37","author":[{"given":"Paula","family":"Arbel\u00e1ez","sequence":"first","affiliation":[{"name":"Department of Analytical Chemistry and Organic Chemistry Universitat Rovira i Virgili  Tarragona Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Judith","family":"Granados","sequence":"additional","affiliation":[{"name":"Department of Analytical Chemistry and Organic Chemistry Universitat Rovira i Virgili  Tarragona Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Francesc","family":"Borrull","sequence":"additional","affiliation":[{"name":"Department of Analytical Chemistry and Organic Chemistry Universitat Rovira i Virgili  Tarragona Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rosa Maria","family":"Marc\u00e9","sequence":"additional","affiliation":[{"name":"Department of Analytical Chemistry and Organic Chemistry Universitat Rovira i Virgili  Tarragona Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eva","family":"Pocurull","sequence":"additional","affiliation":[{"name":"Department of Analytical Chemistry and Organic Chemistry Universitat Rovira i Virgili  Tarragona Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2014,10,15]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.chroma.2011.01.060"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.chemosphere.2012.10.089"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.watres.2008.11.043"},{"key":"e_1_2_7_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.wasman.2012.01.012"},{"key":"e_1_2_7_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.watres.2007.02.012"},{"key":"e_1_2_7_7_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.talanta.2009.06.077"},{"key":"e_1_2_7_8_1","doi-asserted-by":"publisher","DOI":"10.1039\/c1em10260e"},{"key":"e_1_2_7_9_1","volume-title":"Land Application of Sewage Sludge and Biosolids","author":"Esptein E.","year":"2003"},{"key":"e_1_2_7_10_1","doi-asserted-by":"publisher","DOI":"10.1002\/(SICI)1097-0231(19980715)12:13<890::AID-RCM251>3.0.CO;2-X"},{"key":"e_1_2_7_11_1","doi-asserted-by":"publisher","DOI":"10.1021\/es052567r"},{"key":"e_1_2_7_12_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.forsciint.2007.03.002"},{"key":"e_1_2_7_13_1","doi-asserted-by":"publisher","DOI":"10.1093\/chromsci\/46.7.601"},{"key":"e_1_2_7_14_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.trac.2010.03.014"},{"key":"e_1_2_7_15_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.talanta.2013.03.048"},{"key":"e_1_2_7_16_1","doi-asserted-by":"publisher","DOI":"10.1039\/b717453e"},{"key":"e_1_2_7_17_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.chroma.2009.11.033"},{"key":"e_1_2_7_18_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.chroma.2013.10.078"},{"key":"e_1_2_7_19_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.chroma.2010.02.046"},{"key":"e_1_2_7_20_1","author":"Arbel\u00e1ez P.","year":"2014","journal-title":"Chemosphere"},{"key":"e_1_2_7_21_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.chroma.2009.04.059"},{"key":"e_1_2_7_22_1","doi-asserted-by":"publisher","DOI":"10.1021\/es020158e"},{"key":"e_1_2_7_23_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.chroma.2010.08.048"},{"key":"e_1_2_7_24_1","doi-asserted-by":"publisher","DOI":"10.1021\/ac801358e"},{"key":"e_1_2_7_25_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.aca.2010.10.043"},{"key":"e_1_2_7_26_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.aca.2009.11.059"},{"key":"e_1_2_7_27_1","doi-asserted-by":"publisher","DOI":"10.1002\/jssc.200600360"},{"key":"e_1_2_7_28_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.chroma.2013.02.034"},{"key":"e_1_2_7_29_1","unstructured":"Official Journal of the European Communities L221.
