ABSTRACT
Objective To explore the feasibility for determination of chloroform and tetrachloromethane in drinking water with DB-5, Rtx-1 and DB-1 capillary columns. Methods For the mild solubility of chloroform and tetrachloromethane in drinking water, chloroform and tetrachloromethane were analysed by static headspace gas chromatography with DB-5, Rtx-1 and DB-1 capillary columns and electron capture detectorECD, external standard method was used for quantification. Results Three kinds of columns were used for determination of chloroform and tetrachloromethane,the retention time was lower than 3 min, for chloroform and tetrachloromethane the average recovery rates were 92.06%-104.95% and 78.33%-103.22% respectively, RSD were 2.06%-2.71% and 1.76%-5.59% respectively. Conclusion DB-5, Rtx-1 and DB-1 capillary columns are suitable for determination of chloroform and tetrachloromethane in drinking water.
