| Abstract: | [Objective] To establish the method of capillary column gas chromatography for determining nitrochloroform and tetrachloromethane in drinking water.[Methods] DB-5 capillary column and Electron Capture Detector(ECD) were applied for the determination;external label method was used for quantification.[Results] The samples' labeled recovery rates for nitrochloroform and tetrachloromethane were 95.07%~104.80% and 89.94%~96.17% respectively;the RSD was below 2.06%.[Conclusion]This method is simple and rapid to operate and is applicable for the determination of nitrochloroform and tetrachloromethane in drinking water. |
