| 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%。 |

| Abstract: | 7 PCBs in drinking source water was determined by GC/MS with stir bar sorptive extraction （ SB- SE） technique. By optimizing process of extraction and desorption, the results showed good linearity ranging from 5 ng/L to 100 ng/L（ r≥0. 979） ; detection limits of 7 PCBs between 0.8 ng/L and 3.4 ng/L（ 100 mL sam- ple, SBSE extraction 2 hours） ; and spiked recoveries of 10 ng/L standard from drinking source water samples between 93.0% and 116%. |
