In this paper three kinds of methods for the determination of acetaldehyde and acrolein in water are summarized,which are 2,4-dinitrophenylhydrazine derivatization method, headspace gas chromatography and purge-trap gas chromatography mass spectrometry.In addition, respective advantages and characteristics of these methods are showed through the comparison and analysis of the method principles, factors affecting the determi-nation and performance validation.The analysis results on actual water samples by these methods showed that there was no significant difference, and precision and accuracy of these methods all meet the monitoring require-ments.
