| Abstract: | The headspace gas chromatographic method was used to determine dichloromethane in water.The influence of the time and salt effect to the gas-liquid balance were discussed.The detection limit of dichloromethane was 0.001 mg/L,the relative standard deviation were 6.2%-8.7% and the recoveries were 87.7%-110%. |
