摘要:

使用全自动固相萃取仪、C18膜-毛细管气相色谱-电子捕获检测器的分析方法检测水中具有致癌性的卤代醚，回收率范围71.8％～126％，检出限0.5～1.5μg／L，与EPA611相比，更加快速、准确，能够满足我国饮用水和废水的分析要求。

Abstract:

A technique based on automatic solid phase extraction with C18 extraction disk, followed by capillary gas chromatography with ECD, was employed in detecting 5 RCRA haloethers that cause cancer in human. The recovery ratio was between 71.8 to 126% and detection limits 0.5 to 1.5ppb. The technique proved to be much faster and accurate compared with traditional liquid - liquid extractions from EPA611 and can meet the needs for requirements on laboratory water analysis.
