The concentrated extract was cleaned up by dispersive solid\u2010phase extraction with 100\u00a0mg of primary secondary amine as sorbent material. The linearity of this method ranged from 1.25 to 100\u00a0\u03bcg\/L, with regression coefficients ranging between 0.9994 and 0.9999. The limits of detection were in the\u00a0ng\/L level, ranging between 0.2 and 0.3\u00a0ng\/L. The recoveries of seven spiked polychlorinated biphenyls with external calibration method at different concentration levels in tap water, lake water, and sea water were in the ranges of 85\u2013112, 76\u2013116, and 72\u2013108%, respectively, and with relative standard deviations of 3.3\u20134.5, 3.4\u20135.6, and 3.1\u20134.8% (<jats:italic>n\u00a0=\u00a0<\/jats:italic>5), respectively. The performance of the proposed method was compared with traditional liquid\u2013liquid extraction and solid\u2010phase extraction clean\u2010up methods, and comparable efficiencies were obtained. It is concluded that this method can be successfully applied for the determination of polychlorinated biphenyls in different water samples.<\/jats:p>","DOI":"10.1002\/jssc.201700315","type":"journal-article","created":{"date-parts":[[2017,6,22]],"date-time":"2017-06-22T06:24:49Z","timestamp":1498112689000},"page":"3279-3288","source":"Crossref","is-referenced-by-count":7,"title":["Primary secondary amine as a sorbent material in dispersive solid\u2010phase extraction clean\u2010up for the determination of indicator polychlorinated biphenyls in environmental water samples by gas chromatography with electron capture detection"],"prefix":"10.1002","volume":"40","author":[{"given":"Yuanming","family":"Guo","sequence":"first","affiliation":[{"name":"Key Laboratory of Mariculture and Enhancement of Zhejiang Province Marine Fishery Institute of Zhejiang Province  Zhoushan P.R.
