摘要:

建立了用快速、简单、廉价、有效、可靠及安全（QuEChERS）的方法净化、GC/ECD法测定沉积物中有机氯农药〖JP2〗和多氯联苯的分析方法。目标化合物质量浓度在1.0~100 μg/L范围内线性良好，相关系数均＞0.999，检出限为0.08~0.17μg/L。以沉积物标准样品SRM1944为研究对象，用QuEChERS 方法和传统方法进行提取比较，并用沉积物样品进行验证，回收率为87.8%～100.3%。方法快速、简单、可靠、安全。

Abstract:

A quick， easy， cheap， effective， rugged and safe (QuEChERS) clean up procedure was established to determine organochlorine pesticides and polychlorobiphenyls in soils and sediments by GC/ECD. The results showed that the calibration curves were linear in the ranges of 1.0~100 μg / L for target compounds， with correlation coefficients larger than 0.999. The limits of detection were 0.08~0.17 μg/L. The certified reference material of sediment (SRM1944) was chosen as the subject investigated. QuEChERS method was compared with traditional methods， and verified with sediments samples. The recovery ranges were 87.8%~100.3%. This method was demonstrated to be quick， easy， rugged and safe.
