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.
Key words:  haloethers  automatic solid phase extraction  C18 extraction disk  capillary gas chromatography  ECD
