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 detectorECD, 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.
