Abstract:
Objective To establish a method for determination of dichloromethane in drinking water by purge and trap gas chro‐matography‐mass spectrometry .Methods Dichloromethane in drinking water was purged and trapped ,then desorbed and detected by using gas chromatography‐mass spectrometry .Quantitive analysis was conducted by using standard curve under selected ion mo‐nitoring (SIM) mode .Results The operation of this method was simple ,and its limit of detection (LOD) was 0 .005 ng/mL .The recovery rate was higher than 97% ,and the relative standard deviation was less than 5% .Conclusion The method may be appro‐priate to measure dichloromethane in drinking water .
