The optimal condition relevant to the extraction was first investigated, more than 98.7 \u00b1 0.7% recovery was achieved with dichloromethane as extractant, 5 min extraction time, and three cycles of ultrasound\u2010assisted liquid\u2013liquid extraction. Then multiple function was employed to optimize polybrominated diphenyl ether detection conditions with overall resolution and chromatography signal area as the responses. The condition chosen in this experiment was methanol\/water 93:7 v\/v, flow rate 0.80 mL\/min, column temperature 30.0\u00b0C. The optimized technique revealed good linearity (\n                    <jats:italic>R<\/jats:italic>\n                    <jats:sup>2<\/jats:sup>\n                    &gt; 0.9962 over a concentration range of 1\u2013100\u00a0\u03bcg\/L) and repeatability (relative standard deviation &lt; 6.3%). Furthermore, the detection limit (S\/N = 3) of the method were ranged from 0.02 to 0.13\u00a0\u03bcg\/L and the quantification limit (S\/N = 10) ranged from 0.07 to 0.35\u00a0\u03bcg\/L. Finally, the proposed method was applied to spiked samples and satisfactory results were achieved. These results indicate that ultrasound\u2010assisted liquid\u2013liquid extraction coupled with high\u2010performance liquid chromatography was effective to identify and quantify the complex polybrominated diphenyl ethers in effluent samples.\n                  <\/jats:p>","DOI":"10.1002\/jssc.201400507","type":"journal-article","created":{"date-parts":[[2014,8,20]],"date-time":"2014-08-20T21:33:27Z","timestamp":1408570407000},"page":"2874-2881","source":"Crossref","is-referenced-by-count":6,"title":["Optimized determination of polybrominated diphenyl ethers by ultrasound\u2010assisted liquid\u2013liquid extraction and high\u2010performance liquid chromatography"],"prefix":"10.1002","volume":"37","author":[{"given":"Kuang","family":"He","sequence":"first","affiliation":[{"name":"Ministry of Education Key Laboratory of Pollution Control and Ecological Remediation for Industrial Agglomeration Area College of Environment and Energy South China University of Technology  Guangzhou P.
