Abstract:
Objective To establish a method for rapid determination of chlorinated benzene compounds in drinking water.Methods Chlorinated benzene compounds were extracted by purge-and-trap and separated by GC then determined by MS.Results The correlation coefficients of 6 chlorinated benzene compounds were 0.999 1-0.999 8 and the average rates of recovery were 93.0%-97.5%(n=6).The relative standard deviation was 2.45%-4.36%(n=6) and limit of detection 0.007-0.05 ?g/L.Conclusion The method established in the present paper is simple,precious,accuracy and sensitive and applicable to the determination of chlorinated benzene compounds in water.
