GC-ECD双柱分析浦东新区河道鱼体中有机氯杀虫剂残留

Determination of Organochlorine Pesticides Residues in Fish in Rivers of Pudong New Area by GC-ECD and Dual-column Analysis System

使用凝胶渗透色谱净化-气相色谱电子捕获检测器双柱分析,同时测定新鲜鱼肉样品中18种有机氯杀虫剂。采用双柱定性,内标法定量,线性关系、精密度及代用品回收率均良好,同时对浦东内河区域野生鱼样中18种有机氯杀虫剂残留作了定性与定量分析。

18 organochlorine pesticides residues in fresh fish have been determined by GC-ECD at one time.Qualitative analysis was performed by dual-column,and quantitative analysis was performed by internal standard method with good linear relation.The recoveries of surrogate standards were good.The organochlorine pesticides residues of wild fish samples obtained in the rivers of Pudong New Area were analyzed qualitatively and quantitatively.
