Determination of 2-Chloroacetophenone in Water by Solid Phase Extraction-Gas Chromatography

Trace amount of 2-chloroacetophenone in biological water was extracted with a ODS-C18 micro solid phase coulmn,the analyte in eluate was then determined using a capillary gas chromatograph equipped with FID detector.Detection limit was 0.05 mg·L-1 and RSD of the method was 3.0% (for 6 determinations) with recovery of 94%-97%.The method has been applied to the determination of traces of 2-chloroacetophenone in biological water samples.
