| 摘要: |
| 通过对萃取和解吸条件进行优化，实现搅拌棒吸收萃取（SBSE）-热脱附-气相色谱/质谱联用以同时测定饮用水源水中16种多溴联苯单体。此法在2~50 ng/L范围内线性良好，取10 mL水样，搅拌棒吸收萃取1 h后，16种多溴联苯单体的检出限为0.5~1.1 ng/L。对实际水样进行2个质量浓度的加标回收，平均回收率为89.2%~102%。 |

| Abstract: |
| A total of 16 polybrominated biphenyls (PBBs) in drinking source water were determined by GC/MS with stir bar sorptive extraction (SBSE) and thermal desorption technique.By optimizing the process of extraction and desorption,the results showed good linearity ranging from 2 to 50 ng/L.With the sampling volume of 10 mL and SBSE of 1 h,the detection limits of 16 PBBs were between 0.5 and 1.1 ng/L.The recovery test was carried out by standard addition of two concentrations into actual water samples,and the average recovery rates were in the range of 89.2%~102%. |
