Microextraction of the analytes was carried out in the presence of 2-methyl-5-[(Z)-pyridin-4-yldiazenyl]quinolin-8-ol as the chelating reagent. Chloroform and ethanol were used as the extraction and dispersive solvents. Various parameters that influence the microextraction procedure's efficiency\u2014such as pH, centrifugation rate and time, reagent concentration, and sampling volume on the recovery of analytes\u2014were examined. The calibration curves were linear in the range of 0.01\u20131.25 and 0.075\u20135 mg\/L with LODs of 0.25 and 0.84 \u03bcg\/L, and with a preconcentration factor of 94, for Cd(II) and Ni(II), respectively. Precision was &amp;gt;1.0%. The accuracy of the method was confirmed by analyzing the Certified Standard Reference Material (CWW-TMD: Certified wastewater-Trace metals, wastewater). The results show that the dispersive liquid\u2013liquid simultaneous microextraction pretreatment is a sensitive, rapid, simple, green, and safe method for the separation\/preconcentration of cadmium and nickel.<\/jats:p>","DOI":"10.5740\/jaoacint.16-0077","type":"journal-article","created":{"date-parts":[[2016,6,15]],"date-time":"2016-06-15T15:17:06Z","timestamp":1466003826000},"page":"1058-1065","source":"Crossref","is-referenced-by-count":13,"title":["A New Chelating Reagent: Its Synthesis\/Characterization and Application for the Determination of Cd(II) and Ni(II) in Various Food and Make-Up Product Samples by FAAS Using Simultaneous Microextraction Sampling"],"prefix":"10.1093","volume":"99","author":[{"given":"\u015eerife","family":"Sa\u00e7mac\u0131","sequence":"first","affiliation":[{"name":"Erciyes University, Faculty of Sciences, Department of Chemistry, TR-38039, Kayseri, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mustafa","family":"Sa\u00e7mac\u0131","sequence":"additional","affiliation":[{"name":"Bozok University, Faculty of Arts and Sciences, Department of Chemistry, TR-66200, Yozgat, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2019,11,27]]},"container-title":["Journal of AOAC INTERNATIONAL"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/academic.oup.com\/jaoac\/article-pdf\/99\/4\/1058\/32426295\/jaoac1058.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"syndication"},{"URL":"http:\/\/academic.oup.com\/jaoac\/article-pdf\/99\/4\/1058\/32426295\/jaoac1058.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2020,3,19]],"date-time":"2020-03-19T18:15:21Z","timestamp":1584641721000},"score":1,"resource":{"primary":{"URL":"https:\/\/academic.oup.com\/jaoac\/article\/99\/4\/1058-1065\/5658005"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2016,7,1]]},"references-count":0,"journal-issue":{"issue":"4","published-online":{"date-parts":[[2019,11,27]]},"published-print":{"date-parts":[[2016,7,1]]}},"URL":"https:\/\/doi.org\/10.5740\/jaoacint.16-0077","relation":{},"ISSN":["1060-3271","1944-7922"],"issn-type":[{"value":"1060-3271","type":"print"},{"value":"1944-7922","type":"electronic"}],"subject":[],"published-other":{"date-parts":[[2016,7,1]]},"published":{"date-parts":[[2016,7,1]]}}}
