摘要
建立了一种超声辅助萃取,高效液相色谱法检测再生纸制品中多氯联苯PCBs残留的方法。该方法用乙腈-水为流动相,进行等度洗脱,220 nm波长进行检测,16种多氯联苯得到有效分离。该方法对16种PCBs的回收率在90%~104%之间,精密度试验(n=6)的R.S.D<3%,检测限为0.1μg/m L。
To establish a method for the detemlination of polychlorobiphenyls (PCBs) in recycled paper by HPLC with ultrasonic assisted extraction. The extraction was analyzed by HPLC after using a gradient elution program of methanol-H20 as mobile phase, and detected at 220nm. The recoveries of 16 PCBs were 90 %-104 %, the relative standard deviations (RSDs) were under 3 %(n-6), the limits of detection were 0.1 g/mL.
