摘要
首次采用超声波-微波协同萃取的方法对纺织品及纺织品整理剂中的微量全氟辛酸进行提取,通过正交设计法对提取条件进行了确定,并用气相色谱-质谱联用仪(GC-MS)对分析物进行检测.在0～50μg/mL的范围内线性较好,相关系数为R2=0.9999,PFOA检测限为12.6μg/L,回收率保持在80%～100%.最终的处理条件为微波功率200W,萃取时间50min,设定萃取温度70℃,萃取溶剂体积之比为水:甲醇=1:1.
A new method of extracting perfluorooctanoic acid from the textile and textile finishing agent by ultrasonic synergistic-microwave extraction is described for the first time. The optimal condition is determined according to an orthogonal design, and the target substance is detected by gas chromatographymass spectrometer （GC- MS）. The linearity is excellent in the range of 0 - 50 μg/mL, R2 =0. 999 9. The detection limit of PFOA is 12. 6μg/L, the recoveries are in the range of 80%- 100%. The optimal condition is：microwave power 200 W, extrating time 50 min, extracting tempreture 70℃, and the extracting ratio of solvent H2O ： CH3OH= 1 ： 1.
