The main objective of this study was to disperse extraction solvent by using an air-agitated syringe system to overcome matrix effects and avoid dispersion of hazardous dispersive organic solvents by using heat. The DDLL-ME method consisted of two dispersive liquid\u2013liquid extraction steps with chloroform as the extracting solvent. Uranium formed complexes with 4-(2-thiazolylazo) resorcinol in the aqueous phase and was extracted in extracting solvent (chloroform) after the first dispersive liquid\u2013liquid process. Uranium was then back-extracted in the acidic aqueous phase in a second dispersive liquid\u2013liquid process. Finally, uranium was determined by a spectrophotometric detection technique. The variables that played a key role in the proposed method were studied and optimized. The LOD and sensitivity enhancement factor for uranium were found to be 0.60 \u00b5g\/L and 45, respectively, under optimized conditions. Calibration graphs were found to be linear in the range of 5.0\u2013600 \u00b5g\/L. The RSD was 2.5%. Reliability of the proposed method was verified by analyzing certified reference material TM-28.3.<\/jats:p>","DOI":"10.5740\/jaoacint.17-0054","type":"journal-article","created":{"date-parts":[[2017,5,25]],"date-time":"2017-05-25T11:05:09Z","timestamp":1495710309000},"page":"1848-1853","source":"Crossref","is-referenced-by-count":7,"title":["Simple and Rapid Dual-Dispersive Liquid\u2013Liquid Microextraction as an Innovative Extraction Method for Uranium in Real Water Samples Prior to the Determination of Uranium by a Spectrophotometric Technique"],"prefix":"10.1093","volume":"100","author":[{"given":"Naeemullah","family":"Khan","sequence":"first","affiliation":[{"name":"Gaziosmanpasa University, Faculty of Science and Arts, Chemistry Department, 60250 Tokat, Turkey; University of Sindh, National Centre of Excellence in Analytical Chemistry, Jamshoro 76080, Pakistan; University of Turbat, Department of Chemistry, Balochistan 92600, Pakistan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mustafa","family":"Tuzen","sequence":"additional","affiliation":[{"name":"Gaziosmanpasa University, Faculty of Science and Arts, Chemistry Department, 60250 Tokat, Turkey; King Fahd University of Petroleum and Minerals, Research Institute, Center for Environment and Water, Dhahran, 31261 Saudi Arabia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tasneem Gul","family":"Kazi","sequence":"additional","affiliation":[{"name":"University of Sindh, National Centre of Excellence in Analytical Chemistry, Jamshoro 76080, Pakistan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2019,11,22]]},"container-title":["Journal of AOAC INTERNATIONAL"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/academic.oup.com\/jaoac\/article-pdf\/100\/6\/1848\/32426679\/jaoac1848.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"syndication"},{"URL":"http:\/\/academic.oup.com\/jaoac\/article-pdf\/100\/6\/1848\/32426679\/jaoac1848.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2020,3,19]],"date-time":"2020-03-19T18:16:54Z","timestamp":1584641814000},"score":1,"resource":{"primary":{"URL":"https:\/\/academic.oup.com\/jaoac\/article\/100\/6\/1848-1853\/5654289"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2017,11,1]]},"references-count":0,"journal-issue":{"issue":"6","published-online":{"date-parts":[[2019,11,22]]},"published-print":{"date-parts":[[2017,11,1]]}},"URL":"https:\/\/doi.org\/10.5740\/jaoacint.17-0054","relation":{},"ISSN":["1060-3271","1944-7922"],"issn-type":[{"value":"1060-3271","type":"print"},{"value":"1944-7922","type":"electronic"}],"subject":[],"published-other":{"date-parts":[[2017,11,1]]},"published":{"date-parts":[[2017,11,1]]}}}
