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