Established the purge and trap-gas chromatography mass spectrometry determination of chloral in water. Study on reaction temperature and reaction time under alkaline conditions on the transformation effect of chloral hydrate. The linear correlation coefficient was 0.9999 when the standard curve in the range of 1 ~50μ g/L, The recovery was 97% ~ 99.8% and RSD was 0.9%. The method has high recovery rate and good precision, good accuracy, simple operation, fast, suitable for actual analysis.
