A solid phase extraction-gas chromatography method for the determination of trichloroacetaldehyde in surface water was established. The effects of elution solvent, p H value of water sample and sodium chloride addition amount on the extraction efficiency were investigated. The experimental results showed that there was a good linear relationship between trichloroacetaldehyde and chromatographic peak area in the concentration range of 0. 00-50. 0μg/L. The standard recoveries were between 94. 2％ and103. 9％. The relative standard deviations of the seven determination results were less than 3％. The method was simple, high sensitivity, accurate measurement results, good precision, low detection limit, suitable for the determination of trichloroacetaldehyde in surface water.
