摘　　要：通过气相色谱-电子捕获检测器(GC-ECD)对实验室危险废物浸出液中滴滴涕、六六六、六氯苯、氯丹、灭蚁灵五种有机氯农药进行了测定。各组分的线性相关系数均大于0.99,检出限为0.0002~0.05 mg/L;相对标准偏差为1.04%~9.16%。加标回收率为65.7%~118.2%。线性相关性、精密度、准确度均符合GB/T 27417-2017《合格评定化学分析方法确认和验证指南》、HJ 168-2020《环境监测分析方法标准制修订技术导则》方法标准要求。Five organochlorine pesticides including Dichlorodiphenyltrichloroethane(DDT), Hexachlorocyclohexane(BHC), Hexachlorobenzene(HCB),chlordane and Mirex were determined by gas chromatography with electron capture detector(GC-ECD). The linear correlation coefficients of each component were greater than 0.99, and the limit of detection(LOD) were 0.0002~0.05 mg/L;The relative standard deviation(RSD) were 1.04 %~9.16 %. The recovery were 65.7 %~118.2 %. The linear correlation, precision and accuracy met the requirements of GB/T 27417-2017 “Comformity assessment—Guidance on validation and verification of chemical analytical method” and HJ 168-2020 “Technical guideline for the development of environmental monitoring analytical method standards”.
