| 中文摘要: |
| 采用搅拌棒吸收萃取 (SBSE)- 溶剂解吸-气相色谱/质谱联用法测定饮用水源水中7种多氯联苯单体, 优化了萃取和解吸条件。方法在5 ng/L～100 ng/L范围内线性良好 ( r ≥ 0.979),7 种多氯联苯单体的检出限为0.8 ng/L～3.4 ng/L(100 mL水样 SBSE 萃取 2 h), 加标10 ng/L时实际水样回收率为 93.0% ～116% 。 |
| 英文摘要: |
| 7 PCBsin drinkingsource waterwasdetermined by GC/MSwith stirbarsorptiveextraction (SB-SE) technique. By optimizing processofextraction and desorption, the resultsshowed good linearity ranging from 5 ng/L to100 ng/L( r ≥ 0.979); detectionlimitsof7 PCBsbetween 0.8 ng/L and3.4 ng/L(100 mL sample, SBSE extraction 2 hours); and spiked recoveriesof10 ng/L standard from drinking source watersamples between 93.0% and116%. |
