ABSTRACT
In this paper the results obtained using two validated gas-chromatographic procedures on drinking water for the determination of trihalomethanes are compared. The volatile compounds, chloroform (CF), bromodichloromethane (BDCM), dibromochloromethane (DBCM) and bromoform (BF) were detected by purge and trap capillary column gas-chromatography with electrolytic conductivity detector (ELCD) and the simple and rapid gas-chromatographic method by electron capture detector (ECD) after liquid-liquid extraction with n-pentane. For purge and trap ELCD method the response for the volatile compounds was linear for the concentrations of 0.5 to 40 µg/L...
